temperature, and for the dewpoint module, the parameter is dewpoint
temperature. The dewpoint temperature range can be either 0 ... +100 °C
or -40 ... +100 °C.
The probes also have a selectable chemical purge option. Note that with a
warmed sensor head, the probe length is always 90 mm and the sensor is
protected with a sintered filter.
The HMM211 modules are connected to process control systems with
screw terminals. These versatile modules incorporate the
HUMICAP
®
180R humidity sensor which uses an operating principle
based on changes in the capacitance of a thin polymer film as it absorbs
water molecules. The HMM211 modules measure temperature with the
reliable Pt 100 sensor. If the module is ordered with chemical purge
option, it incorporates a composite sensor.
