This new range of KELLER OEM pressure transmitters and transducers 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 silicon sensor is mounted in an all welded oil filled stainless steel capsule, providing a

highly stable measuring cell with negligible hysteresis, unrivalled linearity, high output and a

life of millions of pressure cycles.

The Series 21R use the Series 6 capsule, which is of all welded 316L stainless steel construc-

tion. Transducers 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

reduced 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 procedure 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.
