Chell provides customers with a comprehensive calibration service covering all measurement instruments supplied by the company.
Chell Instruments offer a wide range of high quality and reliable mass flow meters, controllers and systems suitable for use in a wide range of applications and industries.
With over 40 years of experience in flow measurement and control, we are extremely well placed to assist in specifying and supplying instumentation for your application, from single instruments to bespoke automated systems. Chell's impressive calibration and repair facilities also allow us to offer comprehensive after sales support.
Chell Instruments are the UK distributor for the 'SAES Pure Gas' range of gas purification equipment. These offer incredible purification performance over a huge range of gases and flow rates through the use of absorber, adsorber, catalyst, heated getter and palladium membrane purification technologies.
We also supply a range of gas handling solutions, from full, bespoke gas panels to high performance needle valves and regulators.
Chell offer a wide range of equipment for the measurement and control of gas pressure. This could be a very high-end primary pressure standard, benchtop calibrator, portable calibrator or simply a single transducer. We can also provide bespoke, automated pressure measurement systems tailored to your exact process requirements.
Chell's impressive calibration and repair facilities also allow us to offer comprehensive after sales support.
Chell supply a range of temperature scanners to complement the pressure scanners
Chell Instruments offer a wide range of high quality and reliable vacuum measurement instrumentation for use in a huge variety of applications and industries.
With over 30 years of experience in vacuum measurement and control, we are extremely well placed to assist in specifying and supplying instrumentation for your application, from single instruments to bespoke automated systems.
Chell's impressive calibration and repair facilities also allow us to offer comprehensive after sales support.
Intelligent pressure scanner module with engineering unit output.

Up to 0.05% FS accuracy output.
Complete with IEEE 1588 PTPV2 time stamping
Up to 892 Hz per channel measurement frequency.
Output over Ethernet (100Mbit TCP / UDP) and CAN.
Rugged enclosure for on-vehicle applications.
Fully configurable over Ethernet with embedded web server.
The MicroDaq-8 is a further development of the well established Chell MicroDaq range. The MicroDaq-8 is a miniature acquisition system capable of acquir- ing from up to 8 x TE HD DTC or MicroScanner series pressure scanners.
The MicroDaq-8 handles all the scanner interfacing and outputs engineering unit data over Ethernet and CAN.
Like the MicroDaq2, the MicroDaq-8 features hard- ware implementation of the IEEE 15888 PTPV2 precision time stamping protocol and a conventional hardware trigger for data synchronisation.
The MicroDaq-8 also has an embedded web server for all setup functions.
The MicroDaq-8 consists of two high accuracy 18 bit analogue to digital converters (ADC’s) and two powerful processors – one to control the data acqui- sition and one to control the data output interface.
The ADC’s will acquire pressure and temperature data for every data point. The temperature data is used to modify a pressure to compensated pres- sure look-up-table as the measured temperatures change. This ensures that the temperature com- pensation is continuous and doesn’t require the system to stop and acquire temperature data as a separate event.
All the ADC’s, processors and associated elec- tronics are mounted on a single PCB ensuring reliability.
The MicroDaq-8 gives the user access to all the features of a DTC scanners such as 3X derang- ing option and shuttle valve position sense via the Ethernet interface or embedded web server.
The MicroDaq-8 can multiplex the scanners at 14.285 kHz giving a maximum acquisition speed of 892 Hz per channel when 16 chan- nel scanners are used (16MS). When all 512 channels are used (8 x 64 channel scanners), data can be collected at 223Hz per channel.
The data is available over Ethernet which is auto-negotiating 10/100Mbit. The Ethernet output can be configured as TCP or UDP.
For diagnostic purposes, the MicroDaq-8 senses the current sourced by each scanner. In addition, a LED indicates the presence of a DTC scanner on each channel.
The MicroDaq-8 is packaged to enable it to withstand the harsh environments of on-vehicle testing.
