Process indicators now with cylindrical tank volume measurement feature.


A range of process indicators and panel meters with new integrated cylindrical tank volume measurement capability are now available in the UK from instrumentation specialist Impress Sensors & Systems Ltd.

The new feature simplifies the calculation of volumes of liquids, gases or solids in cylindrical process storage tanks. The volume of a combination of different tank shapes can be calculated quickly and easily, including both vertically and horizontally mounted tanks.

The new volume measurement feature is available on a number of process indicators and panel meters from Impress, including the SRL-49, SRP-73, SRP-77, SRP-94, SRP-147 and the SRP-N118. These process indicators and panel meters offer total flexibility in terms of supply options, by offering process manufacturers, OEMs, machine builders, systems integrators and panel builders a wide range of process inputs to suit temperature sensors, voltage and current output devices.

The SRL-49 is a bar graph digital process indicator with current input protection, safeguarding the measuring resistor against damage. Two or four relay outputs enable adjustment of the level of the measured signal. The relay output can be controlled according to one or two threshold values.

The SRP-73 is a compact, low cost, programmable digital process meter, which has a 13mm digital, four-digit, two-colour display. The unit is available with one or two relay outputs. There’s also 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 which 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-147 is a digital process indictor with an extra large 4mm x 38mm display.

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 ABS and glass-fibre. The unit has a 20mm LED four-digit, two-colour display and two relay outputs. The unit also offers signal peak value protection.

All units 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 outputs. All process indicators are available ex-stock from the UK.
