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.
