Vaisala HUMICAP® Humidity and Temperature Transmitter Series
HMP230 The microprocessor-based HMP230 products are versatile and
easy to use transmitters for demanding industrial and air conditioning
applications. The transmitters measure relative humidity and
temperature. As calculated variables they also output dewpoint
and wet bulb temperature, mixing ratio and absolute humidity.
The HMP230 transmitters can be configured to the customer's requirements
on the production line, but configuration and parameters can also be set
by the user. Both analog and serial outputs
are available as well as several options: different cable lengths, power
supply modules, serial interface modules and a local display.
Technical specifications:
- Measurement range: 0 - 100 %RH
- Accuracy against salt solutions: ±2 %RH (0...90 %RH);
±3 %RH (90...100 %RH)
- Max. accuracy against high quality certified
standards: ±1 %RH (0...90 %RH); ±2 %RH (90...100 %RH)
- Operating temperature: -40...+180 °C (-40...+356 °F)
Six models are available:
- HMP231 for wall mounting
- HMP233 for installation directly in processes
in tight spaces
- HMP234 for installation directly in processes
& for measurement in pressures from vacuum to 10 MPa (100 bar,
1450 psig)
- HMP235 for installation directly in processes
& for measurement in temperatures from -40 to +180 °C (-40 to 356
°F)
- HMP237 for most demanding applications
requiring an extremely rugged design
- HMP238 for installations in pressurized
pipelines to as high as 40 bar (580 psig)
