SPECIFICATIONS

Customize Your Instrument
Our unique microprocessor design and modularity allows you to customize the HMP235 at time of purchase:

Selection of output parameters:
Relative humidity Mixing ratio
Absolute humidity Temperature
Dewpoint Wet bulb temperature
 Selection of:
Power supply type (24VDC/VAC; 70VAC, 220VAC)
Cable length (2, 5, or 10 meters)
Local display and keypad
Serial bus type (RS232 or 485)
Mounting flange type (aluminum or stainless steel)
Type of sensor protection (variety of filter types available)
 After purchase, you can directly program either via computer or local display and keypad:
Units (metric or non-metric)
The two output parameters corresponding to analog channels 1 and 2 (note: all output parameters selected by users are also available via serial output and display)
Selection of the following output signals:
4 to 20 mA 0 to 1V
0 to 20 mA 0 to 5V
  0 to 10V
Scaling of measurement parameters and output signals (e.g. -10¡ÆC to +80¡ÆC corresponds to 1 to 5V)
RELATIVE HUMIDITY
Measurement range 0 to 100%
Accuracy (including non-linearity and repeatability)
 Maximum achievable when calibrated against high quality, certified humidity standards:
¡¾1% RH (0 to 90% RH) ¡¾2% RH (90 to 100% RH)
 When calibrated against salt solutions (ASTM E104-85)
¡¾2% RH (0-90% RH) ¡¾3% RH (90 to 100% RH)
Response time (90%) at +20¡ÆC in still air (with sintered filter) 15 seconds
Sensor HUMICAP™ H-Sensor
TEMPERATURE
Measurement range Model 231: -40¡Æ to +60¡ÆC (-40 to +140¡ÆF)
Model 235: up to 392¡ÆF
Accuracy ¡¾0.1¡ÆC
Sensor PT 100 RTD 1/3 DIN 43760B
OUTPUTS
Two analog outputs selectable and scalable 0 to 20 mA 0 to 1V
  4 to 20 mA 0 to 5V
    0 to 10V
Serial output available RS 232C or RS 485
 On-Site, One-Point Calibration
By utilizing a reference TH (or temperature) probe for comparison, routine maintenance and/or calibration of the VA933001/4 can be performed on site within a matter of minutes without disturbing transmitter operation.
This unique one-point calibration feature will save down time, reduce service costs, and ensure high accuracy operation.
