Pressure transmitter goes low with accuracy
Low absolute pressure transmitter is suitable for a wide range of vacuum measurement applications on autoclaves, drying systems, environmental chambers and leak testing.
Digital auto-zero and span option for transmitters
Industrial and precision pressure transmitters incorporate versatile zero and span trimmer that removes the need to adjust potentiometers or use handheld terminals to set the 4 to 20mA current output.
Display plugs in for pressure readout
A novel loop-powered display simply plugs-in between the DIN plug and socket of a pressure transmitter to provide a local indication of the pressure reading.
This sensing technology provides a highly stable and reliable method for sensing low pressures.
The DPS low differential pressure transmitter can be specified in ranges starting from 10Pa up to 1bar which covers a wide range of applications whether you are controlling the differential pressure between two rooms, measuring the differential pressure in a ventilation duct, or detecting the condition of an air filter.
The DPS has a standard linearity of +/-1% full scale with improved linearity options of +/-0.5% FS and +/-0.2% FS, and the hysteresis is better than +/-0.1% full scale.
Despite the low pressure range a good stability figure of +/-0.5% FS per year is typically achieved.
The electronics provide options for a 5 or 10V DC output or a 4-20mA current output in either three- or two-wire configuration.
The supply voltage can be 24V DC or 230 and 115V AC mains providing flexibility for different air control systems.
If a local display of pressure is required an LCD can be integrated into the sensor enclosure.
An auto-zeroing feature for calibration purposes plus relay switch outputs for triggering an alarm are also available options along with the local display.
The DPS differential pressure transmitter provides a solid mechanical design with excellent accuracy performance at a low price.
