The DPGM409 covers the full spectrum in pressure measurement with Gage, Sealed Gage, Absolute, Compound Gage, Vacuum, and Barometric pressure ranges. Its core is a highly stable micromachined silicon sensor with a very high 0.08% accuracy. Each unit is supplied with a 5-point NIST traceable calibration certificate and is tested to industrial CE standards. A user selectable analog output of either 0 to 5 Vdc, 0 to 10 Vdc or 4 to 20 mA is standard on all models and a built-in wireless transmitter option is also available. The electronics are enclosed in a stainless steel and ABS housing that is washdown rated and has a unique magnetic stylus system for programming that prevents accidental programming changes. The display has large 25.4 mm (1 in) digits plus a 0 to 100% bargraph. MIN/MAX/AVG readings are front panel programmable and free data logging and charting software is included. A wireless transmitter option is available to transmit the readings to a receiver in your control room. Power comes from a long life lithium battery (included) with a typical life of 4 years.
