Broad range of process indicators and panel meters

Impress Sensors & Systems Ltdvisit website


A new range of process indicators and panel meters is now available in the UK from Impress Sensors & Systems.

With flexible supply options, the new range of process indicators provides machine builders, process manufacturers, OEMs, systems integrators and panel builders with a wide range of process inputs to suit temperature sensors, voltage and current output devices.

For example, the SRP-73 is a compact, programmable process meter that has a 13mm digital, four-digit, two-colour display. The unit is available with one or two relay outputs. There is also an RS-485 interface for networking to process monitoring systems.

The SRP-94 is a larger programmable process meter that has a 20mm LED digital, two-colour display and up to four relay outputs. The unit provides an active current output that can be taken off to another interface, and sensors can be powered from the unit's dedicated sensor power supply. The SRP-77 is similar to the SRP-94, but offers a two-row display (red and green) panel.

For customers who need to mount the indicator on a wall in a dusty or high-humidity environment, the SRP-N118 is a wall-mountable process meter protected by an IP65 housing made from glass-fibre-reinforced ABS. The unit has a 20mm LED four-digit, two-colour display and two relay outputs. It also offers signal peak value protection.

Remote control

For remote applications where high visibility is required, or where the unit is mounted on the outside of a building, the SWP-457 is excellent. This wall-mounted panel meter provides a 57mm LED four-digit display, housed in an IP65 (standard) or IP67 (optional) protected casing. An optional infrared remote control unit provides identical buttons to the panel meter's own keypad, so that users can program the unit without removing the casing.

Impress Sensors also offers a bar graph indicator, the SRL-49, a two- or four-relay output process meter that provides an easy-to-read, 20-point, two-colour bar graph display. This type of indicator might be used to measure the volume of liquid in a process storage tank or lubricant/coolant reservoir.

There is also a low-cost panel meter option, the SWE-73. These digital indicators are suitable for mounting in large panels, so that users can quickly view multiple displays at once.

All units in the range are available with AC or DC power supply. Input types are voltage, 0-20mA or RTD temperature sensors and provide password protection. Impress Sensors can also supply process meters with different configurations that can take encoder, quadrature and counter-frequency inputs.

All process and panel meters are available ex-stock from the UK. For more information, go to
