Immersion Temperature Transmitter TMI110

For high precision measurements in HVAC applications

The high-accuracy immersion temperature transmitter TMI110 is designed for measuring cooling/heating water temperatures in HVAC automation systems. This exact instrument has a very fast response time to enable precise and reliable controls in HVAC systems.



  • ±0.1 °C / ±0.18 °F accuracy measurement of liquids or air
  • Very fast response time of measurement
  • 1-point traceable calibration (certificate included)
  • Analog (4…20 mA) and Modbus RTU output options
  • Optimized for building automation and HVAC process control
  • Installed in a thermowell for measurement in liquids (types: ASM214691, ASM214707)

High precision

Temperature is measured with a highly accurate Pt1000 sensor element. The high accuracy and quick response time of the measurement enable precise and reliable controls of HVAC systems.

Fast response time

Speed and reliability of measurement are a great advantage in processes of cooling and heating. The fast response time of the measurement allows for instant response in the control loop.

Traceable accuracy

The instruments are individually adjusted and delivered with a traceable (ISO 9001) calibration certificate. The transmitter is easy to calibrate also on site using a Vaisala handheld meter or Vaisala Insight PC software.

Fit for demanding measurement needs

Vaisala provides a wide range of HVAC transmitters to complement the building automation system even in the most demanding indoor environments and their control needs - data centers, other industrial buildings, hospitals, cleanrooms; or monitoring and control of indoor environmental quality in any space where health security matters.
