MARK-10 R08 Series Force and Torque Sensors User Guide

General Overview
Mark10 sensors are designed for use in laboratory and industrial settings. Series FS05 and R07 sensors can also be used with Series F test frames.

Accuracy and Resolution
Indicator accuracy must be combined with sensor accuracy to determine the total system accuracy. The total system accuracy can be calculated by adding the sensor accuracy and indicator accuracy. It is recommended to select a sensor with a capacity as close as possible to the expected load to minimize errors.

Safety / Proper Usage

Note the sensor’s capacity before use and ensure it is not exceeded to avoid damage.
Avoid repetitive shock and impact loading to extend the sensor’s life.

When moving the sensor, lift it from the housing and not from the cable or strain relief to prevent damage.

FAQs (Frequently Asked Questions)

Q: How can I calculate the total system accuracy?
- A: To calculate the total system accuracy, add the sensor accuracy and indicator accuracy. Select a sensor capacity close to the expected load for better accuracy.

Q: What should I do to avoid damaging the sensor during use?
- A: Avoid exceeding the sensor’s capacity, repetitive shock loading, and lifting the sensor from the cable or strain relief when moving it.

OVERVIEW

General Overview

Plug & Test® sensors accommodate numerous force and torque measurement requirements, from 0.25 to 10,000 lbF (1 N to 50 kN) of force, and from 10 ozFin to 5,000 lbFin (7 Ncm to 550 Nm) of torque. These sensors can be handheld or mounted to a fixture or test stand for more sophisticated testing requirements.

Plug & Test® sensors are used with Mark-10 M7I, M5I, and M3I indicators. They may be disconnected from one indicator and connected to another without the need for re-calibration or re-configuration. All such data is saved within a PCB located inside the smart connector.
Series FS05 and R07 sensors may also be used with Series F test frames.

The model number, serial number, and capacity of the sensor are identified in the rectangular label located on the connector. The model and serial numbers are also identified in the Information screen of the indicator. Refer to the indicator user’s guides for more information.

Accuracy and Resolution
Indicator accuracy must be combined with sensor accuracy to determine the total accuracy of the system. Since sensors may be used with the M7I, M5I or M3I indicators, the accuracy of the indicator being used must be identified and taken into account, as follows:

Indicator Model	Accuracy
M7I / M5I	±0.1% of full scale
M3I	±0.2% of full scale

The total system accuracy can be calculated by adding the sensor accuracy and indicator accuracy. Refer to the following examples:

Example 1
Model MR01-100 sensor with Model M5I Indicator

This translates into a fixed error of up to: 0.25% x 100 lbF = 0.25 lbF

Example 2
Model MR50-50Z sensor with Model M3I Indicator

This translates into a fixed error of up to: 0.55% x 50 ozFin = 0.275 ozFin

Because accuracy is defined as a percentage of full scale, the fixed error is possible anywhere on the scale from 0 to the capacity. As such, this value represents an increasingly large error as percentage of reading towards the low end of the scale. It is, therefore, recommended that a sensor is selected with capacity as close as possible to the expected load.

The resolution may be different for some sensors depending on whether a M7I, M5I, or M3I indicator is being used. For example, a Series R01 force sensor will display finer resolution when connected to a M5I indicator than when connected to a M3I indicator. Resolution information is shown in the following sections.

SAFETY / PROPER USAGE

Read through the following safety instructions thoroughly before using a sensor:

Note the sensor’s capacity before use and ensure that the capacity is not exceeded. Producing a load greater than the indicated safe overload value can damage the sensor. An overload can occur whether the sensor’s indicator is powered on or off.
In order to extend the life of the sensor, avoid repetitive shock and impact loading.
When moving the sensor to another location, never lift from the cable or strain relief. This can cause damage to the sensor. Always lift the sensor housing itself.
Always ensure that load is applied axially with respect to the sensor.
Ensure that the sensor is kept away from water or any other electrically conductive liquids at all times.
The sensor and indicator should be serviced by a trained technician only. AC power must be disconnected and the indicator must be powered off before the housing is opened.
Always consider the characteristics of the sample being tested before initiating a test. A risk assessment should be carried out beforehand to ensure that all safety measures have been addressed and implemented.
Typical materials able to be tested include many manufactured items, such as springs, electronic components, fasteners, caps, films, mechanical assemblies, and many others. Items that should not be used with the sensor include potentially flammable substances or products, items that can shatter in an unsafe manner, and any other components that can present an exceedingly hazardous situation when acted upon by a force. Always wear eye and face protection when testing, especially in aforementioned hazardous cases. Extra bodily protection should be worn if a destructive failure of a test sample is possible.
In aforementioned hazardous situations, it is strongly recommended that a machine guarding system be employed to protect the operator and others in the vicinity from shards or debris.
Sensors have threaded holes or chucks, designed for the mounting of grips, fixtures, or attachments. If any such accessories are used, ensure they are mounted firmly to prevent a potential safety risk to the operator and others in the vicinity. If using an accessory from a supplier other than Mark-10, ensure that it is constructed of suitably rugged materials and components. Similar precautions should be taken when mounting the sensor to a test stand, work bench, or other piece of equipment.

SETUP

The Plug & Test® connector must be inserted into the receptacle of the indicator with the side marked “Plug & Test® Technology” facing up (see Fig. 3.1). When fully inserted, the connector will lock into place with a “click”.

To release the connector, press both buttons on either side of the indicator housing (see Fig. 3.2). Pullthe connector completely out of the indicator by holding the curved aluminum section. DO NOT pull on the cable or strain relief.

Press both buttons on either side of the indicator housing to release the Plug & Test® connector.

While holding the force sensor in place with one hand, use an Allen wrench with the other hand to tighten the screw that joins the crosshead to the force sensor, as shown at left.

Optionally cover the screw head with the included black plastic cap.

Overview
Series FS05 is compatible with Series F force testers only. Tension and compression force may be applied to the threaded load cell shaft. Attachments may be threaded onto the shaft. Finger-tighten only.

SERIES R51 TORQUE SENSORS

The attachment and main sensor body mate with a pin and threaded ring.

Unpacking and Assembly
Carefully remove the sensor from the box. Series R51 sensors are available with three interchangeable chuck attachments and bit holder. To attach the chuck or bit holder, align the pin located on the end of the sensor body with the hole located on the attachment (see Fig. 10.1). Thread the ring onto the sensor body to keep the attachment in place.

Overview
Designed for clockwise and counter-clockwise torque testing. The sensor may be handheld or mounted to a test stand, fixture, or other equipment. Bits or fixtures may be placed in the chuck, although extra care should be taken when handling low-capacity models.

Specifications

Accuracy: ±0.2% of full scale
Safe overload: MR50-10Z – MR50-50Z: 300% of full scale MR50-12 – MR50-100: 150% of full scale
Chuck opening range: MR50-10Z – MR50-50Z: 0.062 – 0.375 in [1.6 – 9.5 mm] MR50-12 – MR50-100: 0.078 – 0.5 in [2.0 – 12.7 mm] Operating temperature: 40ºF – 100ºF [5ºC – 38ºC]
Operating humidity: 96% max. (non-condensing)
Weight: From 1.4 lb [0.6 kg]

Calibration
Calibration should be performed in a vertical orientation, especially for sensors with capacities of 50 ozFin [35 Ncm] or less. Horizontal orientation subjects the sensor to side loads resulting from the weight of the chuck and attachments. Such side loads can be significant enough to skew the readings out of tolerance.
The illustration to the right depicts a recommended vertical setup:
For further calibration instructions, refer to the indicator’s user’s guide.
