Anyone who uses ultra-low pressure, vacuum and differential switches can tell you that they will inevitably wear down in low pressure environments, causing contact erosion, loose terminals, switch instability and leakage.
The result? Equipment failure, downtime, and productivity setbacks no busy manufacturer can afford. Fortunately, now there's an alternative-
New Solution to Ultra Low Pressure Switch Problems Helps Avoid Leakage, Set Point Instability and Contact Resistance- an innovation in switch design that combines special gold crossbar contacts with a revolutionary "all-in-one-weld" contact/terminal construction for switches that deliver reliability, long life in harsh, low pressure environments—the MAM005 line of ultra-low pressure, vacuum and differential switches.
Most important, not only do these rugged and dependable switches last longer, they're comparatively priced, no matter if you're just looking for pre-configured switches available for immediate shipping, standard switches tailored to your business needs, or custom-designed switches for special applications

Specially developed for the supervision of clean-rooms, the CPE 300 is dedicated to measures of low pressure andor depression of air or neutral gases from 0/+10 Pa to -1000 /+1000 Pa.
The CPE 300 presents the advantage to become integrated perfectly into walls and to answer to the standard of cleanliness thanks to its stainless case (brushed or with lacquered).
It is equipped with 2 visual and audible alarms, with 2 reversers relays, of a big electroluminescent display and a process of autocalibration which guarantees in the time an excellent stability and a reliability of the measure in low as in high scale.
Thanks to its digital communication (RS 232 and Protocol Modbus RS 485), it offers the possibility of showing alternately (in addition of the measure of pressure) two other parameters resulting from temperature, humidity, velocity or airflow external sensors (KIMO).
Two innovative systems to facilitate the maintenance on-site :
· Its measuring element benefits from the SMART PRO system. It is individually adjusted and is automatically recognized by the device. Thanks to this process, it is possible to replace the measuring element in a simple and fast way without return of the sensor to the factory.
· The calibration in front face : this system allows to proceed to the calibration of the device without un-mounting it.
The sensor CPE 300 is so always operational !

The Series 8 pressure sensors are extremely durable, even when exposed to fast pressure peaks. They have been developed especially for the measurement of high pressures. The Series 8 sensor for ranges 400…1000 bar uses a thicker glass feed through and a wire-bonded measuring cell.
A high-sensitivity piezoresistive silicon chip is used for pressure sensing. The chip is protected against ambient influences by a stainless steel housing sealed with a concentrically corrugated diaphragm. The housing is filled with silicone oil for the transfer of the pressure from the diaphragm to the sensing component.
All metal parts in contact with the pressure media are made of stainless steel AISI 316 L. The fully welded housing is vacuum-tight. The connecting pins allow direct PCB mounting or can be used for connecting cables.

Honeywell Sensing and Control's piezoresistive silicon pressure sensors contain sensing elements that consist of four piezoresistors buried in the face of a thin, chemically-etched silicon diaphragm. A pressure change causes the diaphragm to flex, inducing a stress in the diaphragm and the buried resistors. The resistor values change in proportion to the stress applied and produce an electrical output. These sensors are small, low cost and reliable. They feature excellent repeatability, high accuracy and reliability under varying environmental conditions. In addition, they feature highly consistent operating characteristics from one sensor to the next, and interchangeability without recalibration.
Best Used For:
Medical and HVAC devices, data storage and gas chromatography equipment, process controls, industrial machinery, pumps and robotics.
