Humidity and temperature transmitter
A unique capacitive sensor element is used for measuring relative humidity while temperature is measured by a band-gap
sensor. The applied measuring technology guarantees excellent reliability and long term stability. The microprocessor samples
the humidity and temperature once per second. It calculates an averaging signal over a preset number of seconds and
generates the output signal based on lower and upper signal range values. Standard range is 0…100% RH, -40…60 °C
(-40…140 °F) and 10 seconds average. The signal range of the temperature measurement and the averaging samples may be
customized. Standard output signal range and types may be selected by jumpers. Standard signal ranges are: 0…10 VDC,
0…10 VDC, 4…20 mA and 0…20 mA. Other ranges can be defined by using a programming tool (OPU-S or OPC-S). A version
with display is possible by ordering the integrated display accessory OPC-S.
Minimum and maximum values
Using the programming tool, the user has the option to read out and reset minimum and maximum values. The minimum and
maximum values may as well be used as output signals. The minimum and maximum values are saved into the EEPROM and
are available after a power interruption.
Ordering
Per default a sensor element with 3% RH accuracy and a PG9 cable gland for cables 4 – 8 mm (AWG 6 – 1) is included.
Contact your local sales contact to order sensing elements with different accuracies or if you prefer a sensor with conduit
connectors or a built in display module.
