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.

Gas Handling, Gas Purification Equipment

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.

Gas pressure measurement and control equipment

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.

Vacuum Measurement and Control

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.

CCD100 Display

Single Channel Transducer and Controller Display

This 'Mk3' is an update to our popular CCD100 display. These versatile display/controllers can be used with a huge variety of instrumentation with volt, mV or mA outputs. Examples are mass flow meters/controllers, capacitance manometers and pressure transducers.

Key Features:

• Fully integrated OLED 5 digit display and power supply for a wide choice of gas mass flowmeters, gas flow controllers, capacitance manometers and all-media pressure transducers.
• USB, Ethernet and analogue interfaces as standard.
• Volt, mV and mA configurations.
• Remote setpoint capability
• +/- 15 volt and 24 volt transducer supply.
• 16 bit resolution.
• 0-10 volt set point output controlled from front panel or digital comms.
• Internal webserver for ease of setup and diagnostics. Time stamped data to IEEE 1588 PTPv2 available.
• Two programmable alarm outputs (mechanical volt free changeover contacts).
• HR (high resolution) version available with 6 digits of display resolution and optional input linearisation.

The CCD100 is an established product drawing on 25 years experience of designing and manufacturing displays built specifically to support all makes of capacitance manometers, mass flow meters and mass flow controllers.
It is a single-channel device, distributing power, applying a set point, displaying output and also serving as a digital interface. The set point can be adjusted either manually through front panel controls, or remotely through the rear panel analogue or digital interface.
It features a graphical OLED display that offers large characters, displays any engineering unit, and allows an operator interface that makes configuring the display simple. Much attention has been paid to the menu structure, and in particular the ease of which the set point output can be changed.

The CCD100 contains all the features that could be required of a transducer display, including digital communications, alarm outputs, configurable measurement units and multiple transducer supplies, all as standard. In addition, it has external set point input capability, which can be used by another transducer or input to allow it to be used for gas blending or other ratio control or ‘master / slave’ applications.
Offering both +24vdc and ±15vdc power supplies, it works with most makes and models of transducers with outputs up to 10.8vdc, when used with the correct interconnecting cable. .
The CCD100 is housed within a metal case and takes the form of a standard 1/8DIN panel mount package, but is also built to be fully suitable for free-standing bench-top use.
