APG RP datasheet

RP - Resistive Chain Level Measurement

APG

Flexible by Design

The RP level sensor is designed for use in the chemical, oil, shipping, food processing, waste

treatment, and many other industries. Each RP is manufactured to the users specications making it
t to work precisely according to the application requirements.

Features

• Continuous level indication

• Wide choice of materials

• Durable oat matched to liquid specic gravity

• Resistive chain or loop powered 4-20 mA output

• Hazardous location approvals - Intrinsically safe
