Vaisala HMT120 (mA) RH&T Transmitter

Vaisala HMT120 series Humidity and Temperature Transmitters are designed for RH&T measurement in pharmaceutical and hospital cleanroom type environments and are also suitable for demanding HVAC and light industrial applications.

 

Vaisala HMT120 RH&T specifications…

– Vaisala HUMICAP® sensor technology
– 2-wire configuration with 0/4…20mA output
– Interchangeable probe (easy field calibration)
– Resistant to dust and most chemicals
– Optional LCD display
– Optional Sensor Protection for VHP applications
– USB cable available for maintenance
– Wall-mounted with fixed or remote probe options
– Cleanroom washdown type enclosure IP65

 

The design of the Vaisala HMT120  relative humidity and temperature transmitters is catered specifically towards the cleanroom environment where the instrument can be washed down, is dust proof and is intended for a clean install free of exposed wiring.

 

Vaisala HMT120 RH&T transmitters incorporate the established HUMICAP sensor for a stable and accurate humidity measurement.  In addition, to accompany the pharmaceutical / clean room design of the HMT120, the HUMICAP sensor is resistant to VHP when accompanied by the appropriate sensor protection filter.

 

Product Description

Vaisala HMT120 Relative Humidity and Temperature Transmitters are designed for RH&T measurement in pharmaceutical and hospital cleanroom type environments and are also suitable for demanding HVAC and light industrial applications.  HUMICAP® sensor technology ensures a stable, accurate relative humidity measurement is achieved and all units are supplied with factory calibration certificates as standard.  The Vaisala HMT120 RH&T transmitters have a chemical and dust resistant enclosure design, rated to IP65 and suitable for most cleanroom washdown demands.

The design of the Vaisala HMT120  relative humidity and temperature transmitters is catered specifically towards the cleanroom environment where the instrument can be washed down, is dust proof and is intended for a clean install free of exposed wiring.  Fluidic are able to help with much of your cleanroom instrumentation requirements and we have engineers familiar with ISO13485 environments.

 

The Vaisala HMT120 utilises the established HUMICAP sensor design.  The HUMICAP relative humidity sensor is compatible with direct vaporised hydrogen peroxide exposure, even at concentrations higher than typically used in sterilisation and for hundreds of VHP cycles, up to saturation point. For the applications where full saturation is possible a Vaisala catalytic filter can be specified (model 232637).  More information can be found in the Vaisala VHP application note – click the downloads tab above.

 

Vaisala HMT120 Sensor Protection Options:

  • Standard metal coated PPS plastic, open pore – model: DRW010522SP
  • PPS plastic with 0.2µm pore PTFE membrane – model: DRW010525SP
  • Sintered Stainless Steel with 38µm pore – model: HM46670SP
  • Vaporised Hydrogen Peroxide catalytic filter (Stainless steel) – model: 232637

 

Fluidic are a recognised partner of Vaisala CEN (Industrial division) for Scotland and the North of England.  Our instrumentation engineers are product trained and able to help with instrument selection within the full range of Vaisala Relative Humidity and Temperature transmitters.  In addition we also have a range of cleanroom focused instrumentation for the measurement of pressure, flow, temperature and level monitoring.  Please call either office for more information (Glasgow 0141 641 5920,  Warrington 01925 572401).
