Capsule pressure gauge with electrical output signal
Stainless steel, safety version, high overpressure safety
Models PGT63HP.100 and PGT63HP.160
Applications
Pressure measurement at very low pressures
Acquisition and display of process values for the control room, 4 ... 20 mA, 0 ... 20 mA or 0 ... 10 V
For gaseous, aggressive media, also in aggressive
ambience
Easy-to-read, local analogue display with Ø 100 mm or Ø 160 mm, no external power supply needed
Special features
"Plug-and-play" with no configuration necessary
High overpressure safety up to 50 x full scale value
Measuring chamber protected against unauthorised intervention
Minimal influence on function and measuring error from pressure medium contamination
Description
At any point where very low pressures have to be indicated locally, and, at the same time, a signal is wanted to be transmitted to a central controller or remote control room, the model PGT63HP intelliGAUGE (US Patent No. 8,030,990)
can be used.
Even if the power supply is completely lost, the process pressure can be read securely. The rugged design of the capsule measuring system has an overpressure safety of up to 50 times the full-scale value.
An electronic angle encoder, proven in safety-critical automotive applications, determines the position of the pointer shaft - it is a non-contact sensor and therefore completely free from wear and friction.
From this, the pressure-proportional electrical output signal, e.g. 4 ... 20 mA, is produced. The electronic zero point can also be set manually.
The electronic WIKA transmitter, integrated into the high-quality mechanical pressure gauge, combines the advantages of electrical signal transmission with the
advantages of a local mechanical display.

Design and operating principle
Pressure-sealed measuring chamber (1) with capsule measuring element
The capsule element (2) is pressurised from outside and moves in strokes (deflection)
The deflection is transmitted to the movement (3) and indicated
The overpressure safety is achieved through the mutually supporting surfaces of both halves of the capsule element
