Impress has process indicators and panel meters

A range of process indicators and panel meters is now available in the UK from Aldermaston-based Impress Sensors and Systems.

The range of process indicators offer process manufacturers, OEMs, machine builders, systems integrators and panel builders with a range of process inputs to suit temperature sensors, voltage and current output devices.

The SRP-73, for example, is a compact, programmable process meter, which has a 13mm digital, four-digit, two-colour display.

The unit is available with one or two relay outputs.

It also includes an RS-485 interface for networking to process monitoring systems.

The SRP-94 is a larger programmable process meter, which 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.

The SRP-N118 is a wall-mountable process meter protected by an IP65 housing made from ABS and glass fibre.

The unit has a 20mm LED four-digit, two-colour display; it has two relay outputs and offers signal peak value protection.

The SWP-457 is a process meter that can be mounted in a remote application where high visibility is required, or where a unit needs to be mounted on the outside of a building.

This wall-mounted panel meter provides a 57mm LED four-digit display, housed in an IP65 (standard) or IP67 (optional) protected casing.

There's an optional infrared remote control unit, which 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 a 20-point, two-colour bar graph display, which reflects 0-100 per cent of the measuring range.

This type of indicator might be used to measure the volume of liquid in a process storage tank or lubricant/coolant reservoir.

The SWE-73 is a low-cost panel meter option.

These digital indicators are suitable for mounting in large panels, so that the user can view multiple displays at once.

All units in the range are available with an 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 outputs.
