This new range of KELLER OEM pressure transmitters offers the user the high accuracy and

stability of the KELLER piezoresistive pressure capsule in a low cost OEM package.

Applications include refridgeration, hydraulic controls, air compressors, ink jet printers, vacuum

pumps etc.

The Series 21 R is offered with soldered brass transducers (Series 21 MR), soldered steel trans-

ducers (Series 21 SR) or fully welded (Series 21 R), all providing a highly stable measuring

cell with negligible hysteresis, unrivalled linearity, high output and a life of millions of pressure

cycles.

The transmitters are supplied with 2 metres of screened cable, or a square connector and mating

plug, type mPm-193.

Accuracy is achieved by very large scale predictable production quantities of the pressure capsule

(over 2 million produced today).

Reliability is assured by the inherent properties of the perfectly elastic silicon chip, and ensuring

that neither the pressure media nor the reference media (in the gauge version) come into contact

with any sensitive parts.

Temperature Compensation: Each unit is fully tested and compensated. Span errors are re duced

by selecting the semiconductor doping levels so that the gauge factor of the strain gauges (∆R) is

constant with temperature. Thermal zero compensation is achieved by an automatic test proce-

dure which fits a single resistor across one arm of the bridge.

Shock and vibration performance is excellent due to the silicon chip being suspended in the

oil-filled capsule. It is isolated mechanically from the body. Similarly, the effects of mounting

torque are eliminated.
