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.
