27 Series
86 Series
93 Series
PRESSURE TRANSMITTERS SERIES 27, 86 and 93 use a piezo-resistive pressure sensor. It is a fully active Wheatstone Bridge of resistors diffused in a crystal silicone chip.
The direct conversion of the pressure into an electrical signal is achieved by a minute deflection of sensor which changes the resistance of the bridge with the applied stress. Changes in pressure can cause a corresponding change in the transmitter output in proportion to the bridge unbalance. A single electronic circuit supplies power to the sensor and receives its signal providing conversion into a standard 4-20 mA DC. The circuit card contains the span and zero adjustments.
