Introduction
The Tekmar 078 Universal Sensor is designed for accurate temperature measurement in various applications. It features a robust, stiff jacketed cable for simplified installation into conduits or domestic hot water tank temperature wells. This versatile sensor can also be securely strapped to pipes to monitor supply or return temperatures.
Key Features
- 10K Thermistor: Provides precise temperature readings.
- High Accuracy: Achieves an accuracy of +/-0.2°C.
- Durable Construction: Features a corrosion-resistant brass sleeve.
- Fast Response: Offers very fast temperature response for dynamic monitoring.
- Easy Installation: Stiff jacketed cable facilitates straightforward wiring in conduit.
- Certifications: CSA and C US Approved for use in USA and Canada.
Setup and Installation
The Tekmar 078 Universal Sensor is designed for flexible installation. Always ensure power is disconnected before beginning any installation procedures.
Installation Methods:
- Conduit Installation: The stiff jacketed cable allows for easy pulling through conduit. Ensure the sensor tip is positioned correctly for accurate readings.
- Domestic Hot Water Tank Wells: Insert the sensor tip into the designated temperature well of the hot water tank.
- Pipe Strapping: For measuring supply or return temperatures, securely strap the sensor to the pipe. Ensure good thermal contact between the sensor tip and the pipe surface.
Connect the sensor wires to the appropriate terminals on your control system as per the system's wiring diagram. The sensor is a 10K thermistor type.
Operating Principles
The Tekmar 078 operates as a 10K thermistor, which changes its electrical resistance in response to temperature variations. This change in resistance is then interpreted by a compatible control system to provide an accurate temperature reading. Its fast response time ensures that temperature fluctuations are detected promptly.
Maintenance
The Tekmar 078 Universal Sensor requires minimal maintenance. Regular inspection is recommended to ensure optimal performance:
- Visual Inspection: Periodically check the cable and sensor tip for any signs of physical damage, wear, or corrosion. The brass sleeve is corrosion-resistant, but extreme conditions may still affect it over time.
- Connection Integrity: Ensure all electrical connections remain secure and free from moisture or debris.
- Cleanliness: Keep the sensor tip clean from any buildup that might impede accurate temperature sensing.
Do not attempt to disassemble the sensor. If damage is observed, replace the unit.
Troubleshooting
If the sensor is not providing expected readings or appears to be malfunctioning, consider the following:
- Check Connections: Verify that all wiring connections are correct and secure at both the sensor and the control system.
- Sensor Placement: Ensure the sensor is properly positioned and has good thermal contact with the medium it is intended to measure. Incorrect placement can lead to inaccurate readings.
- Cable Integrity: Inspect the 15-foot cable for any cuts, pinches, or damage that could interrupt the signal.
- Control System Compatibility: Confirm that the control system is compatible with a 10K thermistor type sensor.
If issues persist after checking these points, consult the control system's manual or contact Tekmar technical support.
