H290 is an OEM humidity and temperature product with
an impressive specification. It is particularly well suited
to applications such as climatic chambers and drying
systems. It is available either as a pcb and probe
combination for fitting into the customer’s own
enclosures or housings, and can also be supplied in an
industry standard IP65 case.
H290 provides a linear analogue output of 4...20 mA or
0...10 V from a power supply of 10...35 VDC or
12...24 VAC. In addition, it can be produced with the
digital DIO signal. Temperature measurement is by
direct connection to a Pt100 or thermistor, depending
on the customer’s requirements. Also featured on the
H290 is a compensation system for operation over a
wide -50...200 °C range, with integrated
cable length compensation. This means that whatever
the measurement temperature, or the differential in
temperature between sensors and electronics,
optimum results will be obtained.
