Features

  • Display range: ±1999, ±19990, ±199900 (jumper-selectable)
  • Accuracy: ± 0.1% of reading ± 1 count
  • Powered by 4-20 mA, 10-50 mA or 1-5 mA current loop
  • Maximum 2.5 V voltage drop
  • Easy zero & span adjustment from rear of meter
  • 3 1/2 digit resolution (±1999)
  • High-contrast 12.7 mm (0.50") LCD display
  • Selectable dummy right-hand zeros for display to ±19990 or ±199900
  • 1/8 DIN case with plug-in screw terminals

The Laurel 88-PRO panel meter is a loop powered process display with a jumper-selectable display range of up to ±199900. The 88-PRO can be connected directly to a 4-20 mA, 10-50 mA or 1-5 mA current loop, with no need for additional power to the meter. This is because the meter is powered directly by the current loop, developing a maximum voltage drop of 2.5 V.

By accepting 4-20 mA, 10-50 mA or 1-5 mA signals, the 88-PRO is compatible with a large number of industrial transducers and transmitters to display process variables such as temperature, pressure, flow, weight, pH, humidity etc. Zero and span are adjustable for direct readout in engineering units. There is an INVERT facility, so that an increasing input signal gives a reducing display, for example, 4-20 mA = 100.0 to 0.0. The 88-PRO also provides two jumper-selectable dummy right-hand zero to extend the maximum reading from the default of ±1999 to ±19990 or ±199900. This feature allows the display of large numbers, such as the weight of a truck in pounds. It also useful when the cost of a 4 ½ or 5 ½ digit meter may be too high

The 88-PRO fits in a standard 1/8 DIN panel cutout and only requires 93 mm (3.66") behind the panel. This is less than for most process meters. There are only two signal connections: signal in and signal out. These are made via a detachable screw terminal connector. All range-selection jumpers as well as the meter's zero and span adjustments are from the rear of the meter, avoiding the need to open the case.
