INTRODUCTION

The TR150 Portable Strain Display Load Cell/Torque transducer readout is a microprocessor-based portable instrument designed to interface with any full bridge sensor with an output sensitivity of up to 50mV/V. Bridge resistances from 85Ω upwards can be used with the TR150.
User functions available on the TR150 include:-

  • Range Selection
  • Display Hold/Freeze
  • Gross/Net indication selection
  • Peak Hold selection
  • Trough Hold selection
  • Shunt Cal check

The TR150 is powered by two internal non-rechargeable AA alkaline batteries.
There is an option to have rechargeable alkaline batteries, which can be charged without the need to remove them from the TR150.

USER OPERATION

Ecrane-TR150-Handheld-Load-Cell-Display-fig-5

Important Note
The unit is supplied and calibrated to a particular torque cell. All user functions are available via the front keypad. Do not attempt to re-calibrate the TR150, unless you are authorized and have the equipment available to do so.

There are six push buttons on the front panel of the TR150, which are available for use in normal operation.
Each of these is described below:-

Front Panel Button The function of the Button in Normal Operation Mode
Ecrane-TR150-Handheld-Load-Cell-Display-fig-6 To switch the TR150 ON or OFF press and hold theEcrane-TR150-Handheld-Load-Cell-Display-fig-7  button
Ecrane-TR150-Handheld-Load-Cell-Display-fig-8 The RANGE button allows the user to toggle between two independent scales. The range that has been selected is highlighted by an annunciator.
 

Ecrane-TR150-Handheld-Load-Cell-Display-fig-9

The HOLD button allows you to hold/freeze the current display value when the button is pressed. Pressing the HOLD button again releases the display. The HOLD annunciator is illuminated when in the HOLD mode, and the display will flash, to alarm further that the user is not viewing instantaneous display values.
 

Ecrane-TR150-Handheld-Load-Cell-Display-fig-10

The GROSS/NET button, when pressed, allows the user to toggle between displaying the Gross or Net display values. This can be useful in many applications where it is necessary to display the change in display value from a certain part of the measurement range. When in NET mode the NET annunciator is lit. When in GROSS mode, the NET annunciator is not lit.
 

Ecrane-TR150-Handheld-Load-Cell-Display-fig-11

 

The SHUNT CAL button allows the user to press this at any point in time. The standard unit shunts a 100kΩ resistor across the negative excitation and negative signal connections. If this is performed at the end of the calibration procedure, then a figure can be noted, so the user can check calibration accuracy or connection integrity. The button has to be held down to operate. When held down the SHUNT CAL annunciator is lit and the display will flash, to alarm further that the user is not viewing instantaneous display values.
 

Ecrane-TR150-Handheld-Load-Cell-Display-fig-12

When the PEAK button is pressed the display will show the last Peak reading. To reset the Peak readings press the PEAK and TROUGH buttons simultaneously. When in PEAK mode the PEAK annunciator will be lit and the display will flash, to alarm further that the user is not viewing instantaneous display values. To turn off Peak mode press the PEAK button.
Ecrane-TR150-Handheld-Load-Cell-Display-fig-13

 

When the TROUGH button is pressed the display will show the last Trough reading. To reset the Trough readings press the TROUGH and PEAK buttons simultaneously. When in TROUGH mode the TROUGH annunciator will be lit and the display will flash, to alarm further that the user is not viewing instantaneous display values. To turn off the Trough mode press the TROUGH button

OPERATION FEATURES

NORMAL DISPLAY OPERATION

  • The TR150 has a full 7-digit display, which is pre-scaled by Crane Electronics. The unit can display the instantaneous, peak or trough values. It is also possible to hold the display value (this only operates when not in peak or trough mode).
  • The display update rate, decimal point position and resolution is preset.
  • The TR150 has two independent ranges. All values set in one range are independent from the other.

Switching the TR150 On/Off

  • The TR150 is switched ON or OFF by pressing and holding down theEcrane-TR150-Handheld-Load-Cell-Display-fig-7 button for 3 seconds.
  • The unit will automatically switch itself off after a preset time if there is no keyboard activity.

RANGE Button

  • The range feature allows for the setting of two independent setup ranges to be selected if required. To switch between ranges simply press the range button.
  • An annunciator is lit to identify which range has been selected.

HOLD Button

  • The hold button allows the user to freeze the display when it is pressed. When pressed again the display returns to it’s normal operating mode. When in hold mode the display will flash and the hold annunciator will be lit, to ensure that this feature is not accidentally turned on without the user noticing.
  • The hold feature can not be used when the TR150 is in either peak or trough hold mode.

GROSS/NET Button

  • The gross/net button, when pressed, toggles between the gross and net display values. This enables the user to zero the display (by putting the TR150 into net mode) and display the change in display value from that point.
  • This is useful for certain weighing applications where a tare weight exists, which can be removed by putting the TR150 into net mode.

SHUNT CAL Button
The shunt calibration button, when pressed, puts an internal 100kΩ resistor across the –ve excitation and –ve signal of the sensor, generating a simulated output from the sensor, therefore giving a simulated display value. This can be pressed immediately after the sensor has been calibrated with the TR150 and noted down for later reference. The value noted can be used to get an idea of the calibration accuracy at a later date, or for checking the integrity of the sensor and sensor cabling.
The shunt calibration resistor can be changed to suit specific requirements. It is suggested that a 15ppm ±0.1% tolerance resistor is used.

PEAK Button
When pressed this button puts the TR150 into peak mode. This will display the highest display reading and hold it on the display until it is reset or a higher value is reached. To reset the peak display, press the peak and trough buttons simultaneously. In peak mode it is possible to capture peaks at a rate of up to 25Hz. To turn off the peak mode, press the peak button.

TROUGH Button
When pressed this button puts the TR150 into trough mode. This will display the lowest display reading and hold it on the display until it is reset or a lower value is reached. To reset the trough display, press the peak and trough buttons simultaneously. In trough mode it is possible to capture troughs at a rate of up to 25Hz. To turn off the trough mode, press the peak button.

RS232 Port Connections (WHEN SUPPLIED AS AN OPTION)
The output format is ASCII. The display value is passed to the RS232 port each time the display updates, with a carriage return at the end of each data string. The string information is as follows:-

  • Baud Rate = 9600 baud
  • Stop bits = 1
  • Parity = None
  • Data bits = 8

ELECTRICAL CONNECTION INFORMATION

Sensor Connections
The standard sensor connection is a 5-pin 723 series Binder connector. The sensor connector is also used as a charging socket when the rechargeable alkaline battery option has been ordered, the wiring for this is detailed below:-

  • PIN 1 +ve Excitation
  • PIN 2 -ve Excitation, TEDS Common
  • PIN 3 +ve Signal
  • PIN 4 -ve Signal
  • PIN 5 +ve TEDS

RS232 Port Connections
If the TR150 has been ordered with the optional RS232 output, then this will be available via an 8 pin 723 series Binder connector. The wiring for this is as detailed below:-

  • PIN 1 Tx
  • PIN 2 Rx
  • PIN 3 Gnd
