High performance transducer with adjustable scaling for modifying the pressure range for different applications. Ranges from 0-60 bar up to 0-600 bar gauge or absolute. The output signal is accurate to 0.1% of base range or 0.5% with a 10:1 turn-down, and a 14 bit analogue to digital conversion provides a high resolution amplified output. Optional software and interface kit is available for re-ranging the output signal.

Special Options: Gas and Dust Hazardous area approval Ex II 1 G/D, RS232 software and interface for re-ranging.
The DMP333i has an all stainless steel 316 construction which includes a repeatable high precision silicon strain gauge sensing diaphragm. The precise output from the silicon chip sensor is further linearised and optimised for temperature errors with digital processing amplifier. A high resolution 16 bit analogue to digital converter is used to convert the raw silicon sensor output into a digital signal which is then compensated over pressure and temprature prior to it being converted and amplified to the output signal range.
One of the benefits of a combining high accuracy with a digital amplifier is the ability to to re-scale the analogue output to suit the application whilst maintaining a relatively precise measurement with a significant turn-down ratio. The output amplifier can be configured precisely via a communications kit which includes transducer configuration and RS232 interface cable.
