Applications
For use in inventory management applications, the 8920 Loop Powered Transmitter (LPT) is a precision transmitter designed to relay level or level & temperature information via field communications to the control room. Changes in liquid level and tank temperature are output to a 4-20 mA signal, or via HART (pending). The 20-to-48 DC voltage required for operation may be supplied by the user or through an optional 85-to-305 VAC on-board power supply. Two or four cam-operated switches that can be utilized for indication of alarms or relays are also available as an option.
On Your Tank
The 8920 LPT is easy to install. It mounts directly to most mechanical tank gauges (Varec, GSI, L&J, Sakura).
Complete Tank Gauging System
The 8920 LPT integrates ancillary equipment, and sensors, and provides the first steps to automation and control. It provides an on‐board 3‐wire RTD temperature input. It can activate alarms, SPDT cam-operated outputs, and software-driven contact outputs.
Training and Support
The 8920 LPT is available to ship today. Every transmitter is supplied with detailed user instructions, but sometimes you need to see how it’s done. If you need direct support, we offer standard training and service programs that we tailor to your staff, and your facility.
