902B Abs Piezo
Operation manual
50
Q:
How often does the transducer require calibration or Zero adjustment?
A:
It depends on the application and pressure range but in many applications user adjustment is never
required. Factors that temporarily or permanently can influence the measuring performance is contamination,
corrosion, heat and electronic interference.
Q:
Will the transducer retain user calibration after power is shut off?
A:
Yes - all transducer parameters including calibration data are stored internally in the transducer non
volatile memory.
Service and repair
Q:
+24 VDC supply voltage has been connected to analog . Is the transducer damaged?
A:
Likely - the analog output is not protected against applying power to the output pin.
Q:
Reverse voltage has been connected to power supply input. Is the transducer damaged?
A:
Not likely – the transducer power supply circuit has reverse voltage and over voltage protection however.
MKS cannot guarantee that the transducer will not be damaged.
Q:
If contaminated,
c
an the transducer sensor element be cleaned?
A:
Yes – The Piezo sensor can be cleaned using any solvent compatible with stainless steel 316. Do not
apply any force to the sensor membrane during cleaning. Even small deformation of the membrane structure
will cause permanent damage to the transducers.
