Low Range Pressure Transmitters

Series 41 Absolute, Gauge and Differential Pressure References

The capsule in this transmitter is a KAVLICO capacitive ceramic pressure element, proven in millions of automotive applications, and notable for its excellent long term reliability and stability.

It is enclosed in a sealed stainless steel housing with the diaphragm protected by a gold layer. A neoprene 0-ring seals the sensing diaphragm to the housing.

The transmitter circuit is based on the KELLER "Progres" ASIC, and can be reprogrammed by the user before or after installation (programmable version only). The reference media of the gauge and differential transmitters must be dry air only.

If the reference is likely to be damp or humid, KELLER recommends the use of a purpose built cartridge filled with silica gel which is fitted at the end of the reference tube of the differential transmitter.
