The CMC-99 is low cost compared to existing alternatives on the market and is ideal for a wide range of process applications, including centralised temperature measurement and control; multi-zone heating control; intermediate pumping station control; spraying and heating control for greenhouses; control of industrial furnaces and incinerators; and for engine test cell measurements.

Measuring just 96mm x 96mm x 100mm, the controller housing is very compact, which means the unit can be installed in restricted spaces. The controller has a 3.5-inch backlit colour TFT display and is based on the Linux operating system, with touch-screen menu navigation, offering ease of use and familiarity to the operator. A USB interface is provided on the front of the device, enabling the user to upload or download software programs quickly and easily via a USB memory stick.

PID Control

The controller is available in two power supply versions, 230V or 24V AC/DC. An auxiliary 24V DC/200mA supply output on the back of the unit enables external sensors and actuators to be connected and powered by the controller. The CMC-99 can also act as a PID process controller, providing a reliable control loop feedback mechanism for a variety of process temperature and pressure control applications.

The CMC-99 also comes with a number of communications interfaces, including two RS485 ports, two RS232, a second USB Host and an Ethernet connection, allowing the controller to integrate easily with the customer’s existing process control networks and fieldbuses.

The CMC-99’s integral software provides the user with archiving, printing and visualisation options. A variety of visual presentation display options for recorded measurements are available, including numerical display, bar graph or needle gauge display.

The CMC-99 is also available with a transparent, lockable door to IP42. An IP65 version is supplied with an additional fitted moulded frame.

DS Series Combined pressure transmitter, pressure switch and pressure display

The DS range of pressure transmitter, switch and display combination is a three-in-one multi-function pressure sensor with signal conditioning which gives a current or voltage output signal, 1, 2 or 4 x independent PNP transistor switch outputs and a freely scalable and programmable led rotatable display!  The potential for this device is a complete control system in a single device, cutting installation and equipment costs and configuration to your exact control requirements.

With pressure ranges spanning from 10mbar on the DS 210 through to 600 bar on the DS 200 within the DS series we should be able to cover all requirements on air pressure measurement and liquid pressure sensing alike.  The DS range will cover your requirements for an air pressure transmitter, oil pressure transmitter, hydraulic pressure transmitter and also if it’s just a simple pressure switch that you require then this device will solve that requirement also.

There are several options available within the range including:

1. ATEX certification
2. 1, 2 or 4 switch points
3. analogue output in either 4-20mA, voltage or none!
4. electrical connection
5. process connection type

There’s also the option for a 3-wire 4-20mA configuration which allows for re-calibration of the 4-20mA output signal, not only is the display scalable, the output is also!

The digital LED display on the device is freely rotatable through 2-axis so you will always be able to see the display clearly.  If installed on a vertical pipe horizontally then simply rotate the display through the body until it is face on and then rotate it on the display part so the readings are horizontal.  The brightness is also adjustable depending on the environment you are installing to.

The DS 210 – Air pressure sensor switch

Suitable for air pressure and non aggressive gases, the start of measurement is from as low as 10mbar through to 1000mbar Gauge reference only.  Vacuum pressure ranges also available.

The DS 201 – Ceramic pressure sensor switch and display

Suitable for Gases and Liquids from pressure ranges from 600mbar through to 600 bar Gauge or Absolute reference making this suitable for gauge pressure sensor, absolute pressure sensor requirements and absolute pressure switch applications also.

The DS 200 – Stainless steel pressure sensor switch and display

Suitable for Gases and Liquids compatible with the stainless steel media isolated diaphragm.  Pressure ranges from 100mbar through to 600 bar Gauge or Absolute reference, being based on a silicon pressure sensor with stainless steel diaphragm the over pressure capability is inherently higher and also the resolution is higher than the DS 201 with the ceramic pressure sensor.

The DS 230 – OEM Digital pressure switch with display

Suitable for Gases and Liquids compatible with the ceramic diaphragm and FKM internal O-ring seal.  Pressure ranges from 2 bar through to 400 bar Gauge reference only.  This is a lower cost version with less accuracy and no transmission of output, just purely a pressure switch and pressure display device targeted at OEM applications.

The DS series pressure transmitters, switches and display products are very diverse in their capabilities as a control device, please contact sales for a discussion on to how best implement the pressure product into your application.

SRP-94mV Digital Process Indicator

The SRP range of process indicators and displays supplied by Impress Sensors & Systems Ltd have been upgraded to accept inputs from millivolt (mV) sensors such as strain gauges, piezo-resistive pressure sensors and any other sensing device that will output a mV signal relative to the measurement.

The two standard versions of the SRP that now include the mV are the SRP-73 and SRP 94.  The SRP-73 is 72 x 36 x 97 mm in size and has a 13mm high 4 digit display.  It also has the option of 0,1 or 2 relay outputs which are fully programmable from the push buttons on the front of the device.  It can also be freely scaled to show any engineering units to display the reading.

The SRP-94 is 96 x 48 x 100 mm in case size but has a much larger display at 20mm high and also a 4 digit display.  The SRP-94 has the option of 0, 2 or 4 relays outputs which is excellent for a low-low and high-high alarm system providing a full control system with 2 simple components, a sensor and a indicator to switch on fans, pumps and other controls.  The SRP-94 also has the re-transmission of signal so this can be output to a PLC on additional controller for full PID control functions.  The display colour can also change according to the switch status of the device from RED to GREEN which is a unique function on process indicators!

Both devices are equipped with RS-485 Modbus RTU communications which means they can be accessed, setup and real-time readings by a PC.  When used in conjunction with the supplied software you will have access to ever configurable parameter and tailor the operation of the device to your requirements.

The SRP indicators will also supply a 24V dc voltage to the sensors / transducers so reduces the need to spend extra money on transformers or power supplies to the sensors!  On board maths functions are as standard in the device offering linear, root, square and user defined calculations with a maximum of 20 points.
