FSM PMDS 4 drukverschil transmitter paneel uitvoering

FSM PMDS 4 inbouw drukverschil uitlezing

De FSM PMDS 4 is een universele inbouw display voorzien van een ingebouwde drukverschil transmitter voor o.a. toepassing in clean room, laboratorium of medische ruimten.

De standaard uitvoering is voorzien van een -100 tot +100 Pa druktransmitter, daarnaast kunnen 4 externe signalen worden aangesloten zoals temperatuur of relatieve vochtigheid.

Door zijn beperkte diepte kan de PMDS 4 prima in tussenwanden worden gemonteerd.

Specifications:

Measurement ranges - 100 Pa — 100 Pa (other ranges on request)
Measurement principle inductive
Overloading capability Overpressure recognition pos. overpressure + 1.15 hPa +/- 0.075 hPa
neg. overpressure - 1.15 hPa +/- 0.075 hPa
For differential measurements.

Max. system pressure 1 bar (higher overpressure protection on request)
Medium Non-aggressive gasses
Parts in contact with medium Ni, Al, CuBe, PU
Accuracy* +/- 1 % FS ption: +/- 0,5 % FS +/- 0.2 % FS; other ranges ≥ 2.5 hPa

* The accuracy describes the maximum permissible measurement deviation of the sensor output signal from an applied pressure value.

The accuracy includes measurement errors due to linearity errors, hysteresis errors and repeatability error. Pressure
transducers from FSM are being subjected to a zero point calibration and an amplitude adjustment. Both errors are thereby compensated. The specified accuracy therefore includes the maximum error at room temperature.
