Loop-powered transmitters

April 2003 Maintenance, Test & Measurement, Calibration

GLI has produced a new series of inexpensive loop-powered indicating transmitters, available from PREI Instrumentation. They have been designed for either pH/ORP, conductivity (contacting or electrodeless), flow or dissolved oxygen, and can be panel mounted, surface mounted, or integrally mounted on a GLI sensor.

The main features of these instruments are their low price, compact size, NEMA 4X rating, and their menu-guided operation for set-up, calibration and operation. The LCD display shows the measured parameter, the temperature and the 4 to 20 mA analog output signal, and the power supply can be connected via 2, 3 or 4-wire arrangement. They are CE compliant, approved for hazardous areas, and the calibration settings are protected by a pass code.

These reliable and easy-to-use GLI transmitters are well-established in industries where PLCs or scada systems are used to control plant.
