Product Description

Differential pressure transmitter is a widely user industrial pressure measuring instrument, which can sense the pressure difference between two ports as well as generate an output signal with reference to a calibrated pressure range.

The industrial differential pressure transmitters comprises two housings. Bottom half has a pressure sensing element and top half has the electronics. Both have two pressure ports marked as Low and High. Its not a compulsion that high port will always remain at high pressure and the low port always remain at low pressure. These ports are labeled so because of their relation to the effect of the port on the output signal.

Construction of Differential pressure transmitter

There are three functional parts of a differential pressure transmitter:

Direct Pressure sensing element (based in the lower housing).

Major industrial Direct Pressure Transmitters have a diaphragm as a pressure sensing element. Diaphragm is an mechanical device situated in between the two pressure inlet ports. Applied pressure would deflect this mechanical device. The deflection often is converted into an electrical signal by the sensor. The sensors that could be used in it are:

Differential Capacitance

Strain Gauge

Vibrating wire

The sensor output is proportional to the applied pressure.

Electronic Unit

The sensor in the lower chamber generates electrical signal in the range of milli-volt only. Either the signal is converted to 4-20mA for onward transmission to a remote instrument or amplified to 0-5V or 0-10V range. The DP transmitters upper housing is the transmitter portion that houses the Electronic Unit.

2-Wire 4-20mA Current Transmitter

A DC output current is generated which is directly proportional to the pressure range of the Differential Pressure Transmitter. 20mA is the upper range and 4mA is the lower range. Supply voltage fluctuations and load impedance variation doesnt affect the controlled current output. The 4-20mA output is superimposed with digital communications of HART FSK or BRAIN protocol.

Industrial applications of Differential Pressure Transmitters:

There are many industrial applications of Differential Pressure Transmitters, some of which are listed below:

Monitoring of sprinkling system.
Monitoring of pump control.
In the effluent and water treatment plants, it is utilized for monitoring filters.
Gas and oil flow metering in offshore, onshore and subsea applications.
Monitoring of pressure drops across valves.
Remote sensing of Heating Systems for Hot or Steam Water.
