DIFFERENTIAL PRESSURE TRANSMITTER for low ranges PRE-50G ü Measuring range start from 250Pa ü Output signal: 4-20mA Adapter for valve manifold or steel impulse lines ¼ NPT connector to weld an impulse line (material 316L) PRE-50G Industrial Version, C type process Connector to be mounted along with a valve manifold PRE-50G Economic Version, process connection with terminal connecting to Æ6 pipe (PCV type) An example with PD type Electrical Connection Application The PRE-50G transmitter is applicable to gases, to the measurements of their pressure, underpressure and differential pressure. Typical applications include the measurement of blast pressure, chimney draughts or pressure / underpressure in furnace chambers. IP protection IP65. The economical version can be mounted on any stable construction using the assembly fixture with Æ9 opening. The transmitter’s connection shanks have terminals to be connected to the elastic Æ6×1 impulse line. Where the pulse comes through a metal pipe, we suggest an M20×1.5 adapter for a Æ6×1 fitting using. The transmitter with a C type connector should be mounted on a 3- or 5-valve manifold. We recommend to use our preassembled transmitters with VM type valves (page IV/ 2).
