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.
