GE General Eastern introduces the Modus Series T family of differential pressure transmitters. These differential pressure transmitters measure low pressures and feature low power consumption and a variety of analog signal outputs. A wide selection of standard pressure ranges and electrical ratings is available in the GE General Easter Modus T Series.
Pressure transmitters from the GE General Eastern Modus T Series feature no moving parts to wear out, reliable long term stability, and are virtually position insensitive.
The GE General Eastern Modus Series T pressure transmitters are an excellent choice for many HVAC, process, and automation monitoring requirements. These pressure transmitters monitor: filter differential pressures, fan static pressures, clean room pressures, variable air volume systems, and velocity pressures. Modus Series T pressure transmitters have been used for bubbler level systems, leak detection, and in medical and analytical instruments.
Operation of the GE General Eastern Modus T Series Differential Pressure Transmitter
The pressure sensing element is a differential capacitance cell for pressure measurements ranging from 0.1 to 5 inches of water (25 Pa to 1.0 kPa), or piezoresistive (silicon) sensors for pressure measurements ranging from 5 inches of water to 10 inches of water (1.0 kPa to 2.5kPa).
The capacitance cell is capable of sensing very low pressures, negative or differential. A very light weight, responsive diaphragm within the cell deflects a small amount when a small pressure is applied. This deflection results in a change in capacitance which is then detected and amplified electronically.
The piezoresistive sensor is a solid state device designed in a Wheatstone bridge configuration. When pressure is applied to the device the resistance of the bridge changes by a small amount. This resistance change is converted to a voltage and amplified.
