On stand 1049 at Mtec 2009 (25-26 March), Impress Sensors & Systems will exhibit new pressure and level sensors, including submersible hydrostatic level transmitters, a range of capacitive pressure sensor modules for OEMs, and a new range of miniature pressure sensors.

New to Impress Sensors' stand at Mtec 2009 is the company's IML hydrostatic level transmitters. These are stainless steel, marine bronze or PVC submersible level transmitters that can be supplied with a stainless steel, hastelloy or ceramic pressure sensor. Applications include almost any type of level or depth measurement task, including water tanks, process lines, aggressive media (chemicals) tanks, rivers, sea water, sewage treatment, landfills, tank farms, water treatment plants and early warning flood or tsunami systems. Nominal pressure range is from as low as 0.5mWG up to 200mWG.

An SDI-12 output – a serial data interface at 1200baud – can also be supplied with the IML. This is a standard communications protocol that interfaces battery-powered data recorders with microprocessor-based sensors designed for environmental data acquisition. It enables measurements to be transferred from an intelligent sensor to a data recorder. SDI-12 is suitable for applications where the following are required: battery-powered operation with minimal current drain; the use of one data recorder with multiple sensors on a single cable; or use with microprocessor-based sensors that perform complex calibration algorithms or make internal computations.

As well as level transmitters, Impress Sensors will also showcase its new ME704 capacitive pressure sensors at Mtec 2009. Designed for OEM customers, this ready-to-assemble capacitive pressure sensor module can be configured and programmed via an RS232 interface. The ceramic sensor offers a 10:1 turn down ratio and high overpressure resistance. The sensor can be integrated into any transmitter product, including submersible units. Ranges start from 60mbar up to 20bar.

At Mtec 2009, Impress Sensors is also introducing its ASM miniature pressure transducers to the industrial arena. Originally supplied to the motorsports and other tough automotive sectors as a fuel, oil, air, coolant, brakes and water pressure sensor, the ASM series is now being offered to industrial customers. The rugged all-stainless steel transmitters have a thin-film stainless steel pressure sensor. The housing is made from stainless steel and sealed to IP67. Nominal pressures are from 5bar up to 700bar.

Impress Sensors' product range includes: sensors for pressure, temperature, level and distance measurement; process controllers; process indicators; data logging and recording systems; calibration equipment; and SIL 2-approved and ATEX-approved products. With more than 25 years' experience in the instrumentation industry, Impress Sensors is a rapidly expanding UK manufacturer and distributor, providing expertise in pressure measurement and general instrumentation.
