ARID Adaptor enhances precision and safety in pressure control

23 May 2011

May 18, 2011. With the double adaptor ARID, Baumer enables the combination of their MEX5 safety pressure gauge and their PBSN pressure transmitter. Both instruments are designed for harsh industrial environments with high media temperatures where precision and failure-safety are particularly important. Therefore, the PBSN delivers high-accuracy process data as 4…20 mA output signals while the MEX5 gauge indicates the local pressure. As the MEX5 works on a mechanical basis with no need for electricity, it provides a fall-back option, ensuring that the process can still be controlled in case of a power cut. The resulting increase in process safety is particularly valuable in the harsh and potentially hazardous environments encountered in fields such as energy production, the petrochemical industries, and biotechnology.

The adaptor has one G½ or ½NPT2 connection on the process side and two G½ connections on the side of the measuring devices. It is made of stainless steel 316L and can operate at temperatures of -25…100 °C while being able to withstand pressures of up to 400 bar. The PBSN pressure transmitter delivers a 4…20 mA output signal which is more accurate in this pressure range than the current output signal of a mechanical pressure gauge equipped with an integrated 4…20 mA transmitter.

Since mechanical pressure gauges with integrated 4…20 mA transmitters are relatively expensive, the combination of two instruments through the ARID double adaptor offers a more economical solution. The fact that the ARID adaptor makes it possible to use two measuring instruments on only one pressure port on the process pipe saves further costs because the user is not required to provide additional pressure ports for the additional instrument.
