proCHEM Process Controllers

Product catalog summary

Overview: The proCHEM Series by TPS offers a comprehensive solution for process monitoring, control, and recording. It features a large, easy-to-read LCD display and dual set points for flexible control options. The series is designed for maximum adaptability with standard 4 to 20 mA and 0 to 1 V DC outputs.

Specifications: The proCHEM units are housed in a rugged, non-corrosive, waterproof, and dustproof plastic case compliant with IP65 standards. They operate on 240V AC power, with an optional 12V DC power supply. The units are lightweight, with the instrument weighing approximately 900g and the full kit around 1.5kg.

Control Features: The series includes adjustable high and low set points with visual LED indicators for alarms. The relay outputs are rated at 2 amps at 240V AC, with user-adjustable hysteresis for enhanced control flexibility.

Output and Isolation: The proCHEM series provides galvanic isolation for sensor inputs, though current and voltage outputs are not isolated. Custom 4 to 20 mA outputs can be factory set.

Environmental Specifications: The operating environment for the instruments ranges from 0 to 45°C with humidity levels from 0 to 95% RH.

Sensor Options: Various sensor options are available, including dip-mounted and screw-in sensors for different applications such as pH, Redox/ORP, dissolved oxygen, conductivity, and temperature measurements.

Compliance and Manufacturing: The proCHEM series is manufactured in Australia under the ISO9001:2000 quality system, ensuring high standards of production and support.

Ordering Information: The document provides detailed ordering information for different models and sensor options, including part numbers and available accessories.
