Air velocity sensor

This sensor is used to control the air velocity to a constant value, or to balance out pressure fluctuations (supply or extract air control), or to monitor the flow in air ducts.
It primarily is used for modulating fan control in primary plants to set the basic volume flow.

Supply voltage AC 24 V / DC 12…33 V or DC 7…33 V
DC 0 …10 V or DC 4…20 mA output signal
Measurement unaffected by changes in temperature
High temperature stability
Connection: external thread G ½”, inside thread M5
Maintenance free thanks to outstanding long-term stability
High overload resistance
Robust and compact construction

Process pressure measurement

Pressure transmitters handle a very wide measuring range: from vacuum to extreme pressures
High operational reliability through integrated self-monitoring
High overload resistance, long-term stability and thermal shock compensation of the dry, ceramic-capacitive measuring cell.

Hydrostatic pressure measurement

The temperature of the medium can also be measured
Hydrostatic pressure measurement is not affected by foam generation or vessel internals
Precise adaptation to the process through selection of appropriate measuring cells and housing materials

Differential pressure measurement

Wide application spectrum thanks to large selection of measuring ranges and process fittings
Differential pressure transducers can detect differential pressures of just a few mbar
With an installed chemical seal, media with extreme temperatures can also be safely and reliably measured

Safety Limit Thermostats

Safety temperature limitation, with single-pole changeover microswitch
