The TMI110 temperature transmitter is designed for measuring cooling/heating water temperatures in HVAC automation
systems. When measuring the temperature of liquid, the transmitter is installed in a thermowell, as shown in this Quick
Guide. For air temperature measurements, the transmitter can be installed in a duct using a flange.
The TMI110 temperature transmitter has two output options: analog (4 … 20 mA) and ModbusâRTU. The transmitter's
component board contains a service port, which can be used for field calibration of the device, and for changing the scale
of measurement using Vaisala Insight PC software (available for download at www.vaisala.com/insight).
For the full TMI110 product specifications and user guidance, see TMI110 Datasheet (B212427EN) and HMDW110 Series User
Guide (M211726EN), available at docs.vaisala.com.
