LevelPro® – TPP Series Plastic Temperature Probe

1. Introduction

This manual provides essential information for the installation, operation, and maintenance of the TPP Temperature Sensor. Please read this manual carefully before use.

2. Safety Instructions

• Disconnect power before installation or maintenance.
• Use only within the rated 11-36VDC supply range.
• Confirm process compatibility with PTFE housing material.
• Avoid installing in explosive environments unless certified.
• Ensure proper grounding and wiring to prevent signal issues.

3. Product Overview

The TPP Temperature Sensor is a high-performance, field-mounted temperature transmitter designed for accurate temperature measurement in industrial environments. It uses a PT100 resistance temperature detector and provides a linear 4-20mA output signal.

Constructed with PTFE Teflon, the sensor offers excellent corrosion and temperature resistance, making it ideal for demanding applications across industries such as chemical processing, power generation, food, pharmaceuticals, and textiles.

Diagram Description: The diagram shows the TPP Series Temperature Sensor with a DIN connection and a 1/2" NPT fitting. It also indicates a local display (optional) and the PTFE Teflon construction, noting that a thermowell is not required. The sensor is shown installed in a process vessel.

4. Specifications

5. Working Principle

The TPP Temperature Sensor uses a PT100 element to convert temperature into an electrical signal. This signal is processed by internal circuitry for amplification and compensation. The result is a 4-20 mA output corresponding to the measured temperature. In models with displays, the signal is also converted to a digital format for real-time visualization.

6. Application Diagram

Diagram Description: The diagram illustrates the TPP Series Temperature Sensor installed in a process vessel, showing the sensor's connection to the process and the output signal.

7. Polytetrafluoroethylene (PTFE) Thread Pressure Bearing Capacity

Note: PTFE threads are suitable for low-pressure, corrosive environments and should be used with caution at high temperatures.

8. Dimensions (mm)

Diagram Description: The diagram provides the dimensions of the TPP Temperature Sensor, including the probe diameter, length (customizable), and the 1/2" NPT connection size.

10. Wiring Instructions – DIN Connection

Diagram Description: The diagram illustrates the step-by-step process for wiring the DIN connection of the TPP Temperature Sensor.

1. Loosen the central screw (part 1) and detach the junction box (part 2) from the connector (part 3).
2. Use a screwdriver or similar tool to push out the core (part 4) from the junction box.
3. Loosen the cable gland screw (part 5).
4. Insert the connecting cable through the screw connection (part 5), clamping ring (part 6), and rubber insert (part 7).
5. Connect the wires according to the wiring diagram.
6. Push the core (part 4) back into the junction box (part 2) until it locks in place.
7. Tighten the cable gland (part 5).
8. Reattach the junction box (part 2) to the connector (part 3) and tighten the central screw (part 1).
9. Make sure all seals (part 2, 3, and 7) are properly positioned.

11. Installation Instructions

1. Ensure the power is turned off before installation.
2. Mount the sensor to the process pipe or vessel using the appropriate fitting.
3. Connect wiring as per section 9 based on the sensor's output type.
4. Power on and verify the output signal.
5. For adjustable models, calibrate zero and span if necessary.

12. Maintenance

1. Periodically inspect wiring and terminals for corrosion or damage.
2. Clean the PTFE body with a soft, non-abrasive cloth if exposed to chemical residues.
3. Check for proper signal output using a multimeter or loop calibrator.
4. For display versions, ensure the screen is readable and not fogged.
5. Recalibration is not required unless there is a significant change in process accuracy requirements.
