IMP-LR Low Range pressure transmitter
The IMP-LR pressure transmitter has been designed for applications where the IMP standard industrial pressure transmitter cannot cater for the pressure ranges. The IMP is limited to 500mbar as it uses a ceramic based piezo-resistive pressure sensor but the NEW IMP-LR offers pressure ranges from as low as 25mbar through to 1000mbar gauge, absolute ranges also available on request.
Based on an Oil filled isolated diaphragm silicon pressure sensor the IMP-LR can offer accuracy of <0.25% as standard with the option of linearity correcting to <0.1% FS BFSL if required. Being an isolated diaphragm silicon pressure sensor the transmitter can be used on both liquids and gases. The sensor is installed in the stainless steel housing and sealed on an O ring which means by selecting the correct material these pressure transmitters be used on a wide variety of applications and medias.
The pressure transmitter is built in our factory in Aldermaston in a modular format so when required it is taken from stock pre-assembled. We then calibrate the sensor using the automated calibration system via the ASIC based digital electronics. This means there are no internal pots giving a very stable output with good long term stability. The transmitter build is finished by simply selecting the correct electrical connector and issuing the calibration certificate which comes as standard with every sensor. The choice of electrical connections include both small and large Hirschmann style plug & sockets, M12 and binder connectors, IP66 and IP68 cable glands and MIL-Spec connectors also.
Available outputs include the standard 4-20mA current and a variety of voltages both ratiometric and non-ratiometric all of which are temperature compensated as standard. The IMP-LR is also suitable for all types of installation and complies to the latest standards in CE, EMC and RFI protection.

IMD Differential Pressure Transmitter
The IMD Differential pressure transmitter has been developed to cater for applications that may only be looking at a low level of differential pressure (from 350mbar) but with a HIGH static line pressure up to 200 bar!
The IMD has a differential pressure range from 350mbar through to 35 bar and can have a nominal static line pressure of up to 200 Bar which makes this product ideal for low differential pressure measurement across a filter on a pipe or manifold that may have excessively high line pressures. This has always been an issue for applications and usually results in customers compromising on the resolution and accuracy by using a higher pressure range than what they actually need to achieve the high line pressure requirements! Outputs include 2 and 3 wire 0/4-20mA and voltage outputs which are ideal for most conventional HMi’s, PLC’s, signal conditioners and data loggers.
IMD, has a piezo‐resisitive stainless steel isolated diaphragm and is suitable for
use with liquids or gases. The housing and sensor is made from stainless steel and with an internal Viton O ring seal
making this product suitable for a wide range of applications. Every device is temperature compensated and
calibrated and supplied with a traceable serial number and calibration certificate. The integrated electronics can be
configured to have either voltage and current outputs with zero and span adjustability via the internal Pots. With
optional ATEX approval to EEx ia IIC T6 extends the possible applications to Petrochem & Process Industry.
The sensing technology used within the IMD is a strain gauge fabricated as part of the silicon chip. This is then isolated from the media by means of an oil filled cavity and a stainless steel diaphragm which enables the product to be used with liquids or gases. The housing and sensor is made from stainless steel and incorporates an internal Viton O ring seal making this product suitable for a wide range of applications. Every device is temperature compensated and calibrated and supplied with a traceable serial number and calibration certificate. The integrated electronics can be configured to have either voltage and current outputs with zero and span adjustability via the internal Pots.
With optional ATEX approval to EEx ia IIC T6 extends the possible applications to Petrochem & Process Industry, other applications include the following:
- Hydraulics
- Pneumatics
- Filter condition monitoring
- Agricultural machinery
- Laboratory testing
- Mechanical engineering
- Environmental engineering
- Automotive testing
- Pumps & compressors
- Medical testing
- Waste water & sewage
Other applications for differential pressure measurement include tank level measurement in a sealed vessel where the air pressure in the top of the tank is measured relative to the hydrostatic pressure of the liquid in the vessel. Flow measurement in a pipe by means of an orifice plate which creates a differential pressure dependant on the size of the orifice plate. More can be seen about applications and typical installations following this link.

IMP Industrial Pressure transmitter
The IMP Industrial pressure transmitter is now offered on a standard 4 day delivery which CAN be improved for urgent requirements!
The IMP is built on a Kan-Ban basis so part assembled bodies are held on the shelf ready for calibration via the ASIC based Microprocessor and all that is required then is the electrical connector to be fitted as specified by the customer. This enables production to perform a quick pressure range of the device, calibration and installation of Electrical connection. The options include Plug & Socket, IP66 Cable, IP67 Cable M12 Connector, Amphenol Connector and others on request.
The Pressure transmitter is based on a piezo‐resisitive ceramic pressure sensor giving it excellent media compatibility. The housing is made from stainless steel with a choice of internal O ring seals to ensure the product is suitable for a wide range of applications. Every device is temperature compensated and calibrated and supplied with a traceable serial number and calibration certificate. The electronics incorporate a microprocessor based amplifier, this means there are no adjusting pots and therefore the electronics are very stable, specially in high vibration / shock applications.
We cover pressure ranges from 500mbar through to 700 bar with this product and have options for Absolute, Gauge and Sealed Gauge reference. The electrical outputs available are mV, Volts and 4-20mA Current output as standard. If your application requires improved performance from the standard<± 0.25% then we can offer a <±0.1% within 7 days delivery on any pressure range.
IMP pressure transmitter up to 150°C
We have options of different housing material such as PVC, PVDF & PEEK to solve applications with aggressive chemicals. The ceramic sensors are ideal for these applications as they are virtually inert. We can also supply a version which has an integrated temperature cooling element. This will enable the transmitters to be exposed to 150°C media temperatures!
