The Endress+Hauser Thermophant T TTR31 temperature switch is designed for reliable temperature monitoring and switching control in industrial processes.

It combines measurement and switching functions in one compact device. When a set temperature is reached, it can directly trigger alarms, start/stop equipment, or activate protection systems.

Typical use:

• Equipment protection
• Cooling system control
• Process temperature monitoring

Not suitable for:

• High-precision temperature measurement only (no control needed)

Technical Information Thermophant T TTR31

 When Should You Use a Temperature Switch?

Choose the TTR31 if your application requires:

• Automatic ON/OFF control based on temperature
• Equipment protection (e.g. overheating shutdown)
• Simple integration without a full control system
• Replacement of mechanical temperature switches

If you only need temperature display or logging, a transmitter is more suitable.

 What Makes It Different?

1. Measurement + Switching in One Device

Unlike traditional setups, this device combines:

• Temperature measurement
• Switching output

 No need for separate controller + sensor.

2. Fast Response for Equipment Protection

It reacts quickly when temperature reaches the set point.
Helps prevent overheating and equipment damage.

3. Compact and Easy Installation

The integrated design reduces wiring and installation effort.
Ideal for machines, pipelines, and compact systems.

4. Digital Configuration and Display

Users can easily set switching points and monitor values.
 Improves usability compared to mechanical switches.

 Typical Applications

Pump and Motor Protection
Automatically stop equipment when temperature exceeds limits.

Cooling Systems
Control cooling activation based on temperature thresholds.

Process Pipelines
Monitor and control fluid temperature in real time.

 FAQ

Q: Is this a replacement for a temperature transmitter?
A: Not exactly. It is designed for control (switching), not just signal transmission.

Q: Can it directly control equipment?
A: Yes. It provides switching outputs to trigger alarms or control systems.

Q: What is the main advantage over mechanical switches?
A: It offers higher accuracy, easier setup, and better reliability.
