ASHCROFT Sanitary Pressure Transducer

What safety precautions do we take while operating these Ashcroft KS sanitary pressure transducers?

• These sanitary pressure transducer's pressure measuring elements may get damaged electrically or mechanically when the media pressure spikes beyond the rated overpressure capability of the transducers.
• Avoid fluid hammers (occur when the liquid flow stops suddenly) and surges (occur when the flow starts suddenly) to ensure proper measurement of the pressure transducers. Users can avoid fluid hammer & surge damage by installing a surge chamber in the fluid line.
• Flow valves should also be opened or closed slowly to avoid damaging the instrument.
• The transducers should be grounded before making any electrical connections to avoid static electrical charges.
• Ashcroft KS sanitary pressure transducers should be mounted in locations having minimum vibration.
• Do not run the power cables of Ashcroft KS sanitary pressure transducers near any inductive equipment for minimum noise susceptibility.
• Check for corrosion on the pressure containing parts of the transducers before operating for accurate pressure measurements.

Where is Ashcroft Inc. located?

Ashcroft, a leading manufacturer of temperature & pressure instruments, is located in Connecticut, US

Where are pressure transducers having diaphragm seals used?

Pressure transducers having diaphragm seals, such as Ashcroft KS sanitary pressure transducers are used where the critical medium can not come in direct contact with the measuring instruments. The diaphragm in these pressure transducers separates the abrasive, aggressive and critical medium from pressure instruments to measure pressure in high-temperature applications. They are also suitable for compact locations where traditional pressure measuring tools, such as pressure gauges, can not be used.

What is the difference between voltage & current output sanitary pressure transducers?

Ashcroft KS sanitary pressure transducers (having current outputs between 4 to 20mA) are not affected by electrical noise and power supply resistance. They are therefore ideal for pressure measurement in media at a long distance.
Ashcroft KS sanitary pressure transducers (having voltage outputs between 1 to 5V) feature integral signal conditioning for less susceptibility to electrical noise. They are suitable for use with an unregulated power supply.

Are a transducer & transmitter the same?

Most people confuse these terms and use them interchangeably. But no, transducers and transmitters are not the same. Transducers convert a physical variable like temperature or pressure into an analogue electrical signal (generally low voltage). Transmitters convert this low voltage or current signal from the transducers into a much larger electrical signal for long-distance transmission to a PLC sensor or switch. A pressure transmitter is connected to the pressure transducer.

What are diaphragm pressure switches?

Ashcroft diaphragm pressure switches are used to monitor & control pressure in hydraulic & pneumatic systems to prevent damage and downtime. They automatically cut off / start the system at pre-set pressure settings.
