Pressure transmitters for standard
filter housings
Walker Research has launched its ESD series of low cost pressure switches and 4-20mA transmitters, designed to measure differential and gauge pressure of inert fluids across a range of applications
Even though differential pressure has a direct bearing on energy consumption, very few firms properly acknowledge associated costs Keeping tabs on differential pressure through continuous monitoring can help companies to keep abreast of energy consumption whilst maximising their use of filtration and air treatment equipment

Historically, the evolution and choice of monitoring devices offered through the compressed air market channels have remained relatively static.
A majority of companies rely on differential pressure gauges to provide snapshot indications of filter efficiency and performance.
Differential pressure across a filter is always in a state of flux; it varies considerably depending both on its own performance and changing demands placed on the air compressor.
Companies using Differential Pressure gauges run the risk of reporting pressure drops that don't correctly or accurately reflect trends over time.
There is a clear need for continuous monitoring of both gauge and differential pressures across compressed air treatment systems.
There have been several piecemeal products offered to the market; their strategic thrust has focused on filter replacement.
The types of products that might offer superior benefits are those that give users the flexibility to interrogate data.
The next step is in fact to take a step back and examine the technology platform used across industry and the manner that it is integrated into centralised control panels and data acquisition equipment.
The most commonly recognised vehicle for data transmission is a 4-20mA analogue signal.
Walker Research has launched its ESD series of low cost pressure switches and 4-20mA transmitters, specifically designed to measure differential and gauge pressure of inert fluids across a wide-range of applications.
The use of special adapters ensures that devices can be easily mounted directly onto 'leading' manufacturers' filter housings, where normally a differential pressure gauge would affix.
Transmitter devices are available in multiple formats: differential, gauge, differential and gauge, all in an extensive line of pressure ranges.
