Vaisala HMW90 Series [TMW93] Temperature Transmitter

TMW93 Temperature Sensor for High Performance HVAC, Wall Model, Voltage Outputs, 0.2°C accuracy.
The 3-wire TMW93 transmitter is designed for use in high performance HVAC applications such as museums, laboratories, data centers, and production facilities. The transmitter is quick and easy to install and use on the field even without any special tools. The most common settings, such as metric/non-metric unit selections, and relay set-point, can be easily changed with dip switches when the enclosure is open.

On-site calibration and adjustment is exceptionally easy. The sliding cover lid exposes offset trimmer for 1-point calibration of temperature. The included display makes adjustment clear and convenient by instantly indicating the effects of any changes. A service port enables temperature calibration, using either a PC or the Vaisala HUMICAP® Hand-Held Humidity and Temperature Meter HM70.

The transmitter also features a user exchangeable temperature module TM10, which can be ordered as a spare part. The module is delivered with a calibration certificate.

Analog output, display units, and relay set-point are preset at the factory to:

• Channel 1: 0...10 V = -5...+55°C (+23...+131°F) T
  
• Display: metric units
