Pressure sensors that combine hygiene with economy

Jan 2000 Sensors & Transducers

IFM Electronic's new range of flush-mounting pressure sensors has become an attractive choice for applications in the food, beverage and pharmaceutical industries. The reasons include hygienic construction - approved by the European Hygiene Equipment Design Group (EHEDG) and the FDA in America, the ability to withstand temperatures as high as 145°C and the attractive pricing.

All sensors in the new range use IFM's innovative ceramic cell pressure sensing technology which provides stable, accurate operation with freedom from ageing effects and which ensures outstanding resistance to over-pressure damage. Easy adjustment is provided by a microprocessor-based pushbutton-operated set-up system, and an integral three-digit seven-segment display which confirms settings as they are entered.

IFM hygienic pressure sensors are available in versions to cover pressure ranges of 0 to 1, 0 to 2,5, 0 to 10 and 0 to 25 bar. All types can be supplied with the popular 3/4" and 1" BSP cone fittings, or for use with M0 adapters which include DIN 11851, Tri-Clamp and Varivent options. Pricing for all types is very competitive, with a complete sensor typically costing less than the traditional seal often used for hygienic applications.

Hygienic pressure sensors from IFM Electronic are offered with a choice of standard or extended operating temperature ranges. Standard temperature range sensors are suitable for use with working fluids between -40 and +80°C, while extended temperature range versions can withstand continuous fluid temperatures of up to +125°C.

The sensors can also withstand temperatures as high as +145°C for periods of up to one hour, making them ideal for installations where steam or hot liquids are used for cleaning and sterilisation.

For maximum versatility, the sensors provide a switching output, which can be programmed as normally open or normally closed, as well as a linear 4 to 20mA analog output. Analog signals have an accuracy better than ±1% of the full operating range, and no calibration is required.
