Pressure transmitters built for heavy duty hydraulics applications

Paul Boughton

A range of stainless steel welded pressure transmitters for heavy duty hydraulics applications is now available from instrumentation specialist Impress Sensors & Systems.
The new robust 17.600 G pressure transmitters have a stainless steel housing, pressure port and diaphragm and require no O-ring seals. The transmitters can operate in temperatures from -40˚C to +125˚C, making them ideal for heavy duty OEM hydraulics applications, including mobile hydraulics equipment, off-highway and construction vehicles, heavy duty hydraulic presses, geotechnical testing machinery and other applications where high pressure hydraulic rams or cylinders are present.
The sensors offer high overpressures (typically three times the nominal pressure rating) and so are ideal for use on mobile hydraulics equipment and heavy duty hydraulic presses, where pressure spikes or peaks are likely to occur.

The 17.600 G pressure transmitter is available in nominal pressure ranges from 0– 6 bar up to 0–600 bar. This means the sensors can measure pressures in a vacuum, as well as being resistant to vacuum conditions. The sensors also offer up to three times overpressure or higher.

The sensors can withstand vibration up to 20g (according to DIN EN 60068-2-6) and shock to 500g (according to DIN EN 60068-2-27). Standard output is 2-wire, 4–20mA, with optional 3-wire, 0–10V or 3-wire ratiometric also available.
