1. Two types: industrial standard type (UPB40-a) and generally simple type(UPB40-b);
2. HART Protocol or MODBUS Protocol option

UPB40 series high system pressure silicon differential pressure transmitters are one kind of differential pressure measurement instrument with light weight, high performance and high working pressure.

The products use small type silicon differential pressure sensor assembly (outer diameter 40mm), which have compact structure and system pressure protection. The superior characteristics of sensors enable UPB40 can be assembled to not only industrial standard type differential pressure transmitters (e.g. 3351 series), also composed to easy general type of micro-differential pressure transmitter with high working pressure . Meanwhile, for general type of UPB40, it have exhaust valve for option

UPB40 series high system pressure silicon differential pressure transmitters are designed for precision measuring for liquid, or gas's pressure, differential pressure and negative pressure. When UPB40 iscoordinating throttling element, it can also measure liquid's flow. Besides 4~20mA analog output, UPB40can also be made with HART Protocol or RS232,RS485 communication interface. UPB40 are widely used for pressure measurement and control in many industrial process.

Features:

*Two types: industrial standard type (UPB40-a) and generally simple type(UPB40-b)
*2-wire 4~20mA output signal, HART Protocol or other communication interface are optional.
*Advanced diaphragm manufacturing and weld process, entirely sealed oil-filled isolation technology, unidirectional system pressure protection, can withstand max. rated working pressure
*Good long term stability
*High accuracy
*Measuring range continuously adjustable, and rangeability can be positive and negative
*Good performance of electromagnetic compatibility
