The 88-PRO Process Meter may 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. It fits in a standard 1/8 DIN panel meter cutout and is only 93 mm (3.66") deep. There are only two signal connections: signal in, signal out. Readout in engineering units. 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 Easy to install and set up. 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. Attractive and easy to read. The facia of the 88-PRO is attractively styled. The simple bezel will compliment your panel design. The lens protects all legends and markings, so repeated wipe-downs won't damage the lettering or display clarity. High contrast LCDs make these meters suitable for use in bright environments. The digits measure a full 12.7 mm (0.50"). The price is $175. For more information, visit www.laurels.com/88pro.htm
