The PM 620 is the latest development in digital output sensor
technologyincorporatinganumberofkeyinnovationstoallow
pressurere-rangingofcompatibleequipment.Asimplescrewt
makesboththepressureandelectricalconnectionswithoutthe
needfortools,sealingtape,cablesorplugsanddigital
characterisation allows interchangeability without set-up or
calibration. The modules can be changed in a few seconds to
re-range an instrument at a fraction of the cost of a new one.
The pressure modules can be used in conjunction with the
relevant pneumatic or hydraulic pressure station and the DPI 620
multifunction calibrator to form an integrated pressure calibrator
for test and calibration of pressure instruments including
transmitters,transducers,switches,gauges,indicatorsand
recorders.Alternatively,themodulescanbecombinedwiththe
pressurestationbyamodulecarrier,whichaddsadualchannel
pressure measurement capability that can be re-ranged in seconds.
