PRESSURE TRANSMITTERS

GSI offers a broad range of gauge, absolute, or differential pressure smart transmitters.  From vacuum service to more than 7000 psig, we can select the best instrument for your pressure measurement or control application.

Gauge: Absolute

Differential

Diaphragm Seals

Gauge Absolute Pressure Transmitters

Utilizing field proven resonant pressure sensing technology, these accurate and robust sensors measure gauge and absolute pressure. Gauge pressure transmitters measure pressure in relation to atmospheric pressure and absolute versions measure pressure in relation to vacuum. Pressure ranges can be measured as low as 0-0.1 inches of water and as high as 0-7250 psig. 

Gauge Differential Pressure Transmitter

Utilizing field proven resonant pressure sensing technology, these accurate sensors measure differential pressure. Differential pressure instruments measure the difference between two applied pressures, which is most common in flow, and level measurement. Transmitters are two-wire type with 4-20 milliamp output signals or digital communication such as FIELDBUS, ProfibusÔ, or HART. Differential pressure ranges can be measured as low as 0-0.1 inches of water and as high as 0-2000 psid at static pressures up to 4500 psig. 

Diaphragm Seals

Diaphragm seals are used to prevent process medium from entering directly into the pressure-sensing assembly of the pressure or differential pressure transmitter.  They are connected to the transmitter with capillary tubes of various lengths.  They are used for viscous, corrosive, or high temperature fluids.
