Vaisala TMI110 immersion temperature transmitter is highly accurate and designed for measuring water temperatures in HVAC systems. It can also measure air temperatures in ventilation ducts. With its fast response time, it ensures precise control of HVAC systems. The TMI110 is part of the Vaisala HUMICAP® Humidity and Temperature Transmitter Series HMDW110, which offers various transmitter options for different mounting need

Highly Accurate

Vaisala TMI110 is a highly accurate temperature transmitter. It measures liquid temperature in cooling/heating systems and air temperature in ventilation ducts. For liquid temperature, it’s installed in a thermowell, and for air temperature, it’s mounted in a duct using a flange. It uses a Pt1000 sensor (class A) for temperature measurement, ensuring precise control of HVAC systems with its accuracy and fast response time.

Fast Response Time

Vaisala TMI110 prioritizes fast measurement response for instant control loop feedback. Its speed and reliability are crucial for accurate cooling and heating process measurements, making it ideal for building automation and HVAC control.

Traceable Accuracy

All Vaisala TMI110 transmitters are individually calibrated and comes with a traceable (ISO 9001) calibration certificate. If needed, it can also be calibrated in the field using a Vaisala handheld meter or Vaisala Insight PC software.
