VAREC 2920 Float & Tape Transmitter - FM Approved N2920-FM-1-MS-0-N

Varec 2920 N2920-FM-1-MS-0-N Float & Tape Transmitter - FM Approved Description The Varec 2920 Float & Tape Transmitter (FTT) is a tank-side device designed to convert precise mechanical level measurements from float and tape tank gauges into reliable digital data for inventory management and automation systems. Using an absolute capacitance encoder with direct-drive gearing, the transmitter delivers high accuracy and repeatability without batteries or wearable components. It integrates seamlessly with existing tank gauging systems, supports multiple industry-standard communication protocols, and accommodates ancillary devices such as temperature sensors, HART instruments, alarms, pumps, and valves. Built for hazardous environments, this FM-approved configuration is engineered for long-term reliability, simplified installation, and robust performance in demanding bulk liquid storage applications. Features Absolute Encoder Technology: Capacitive absolute encoder provides highly accurate, maintenance-free level measurement with no battery backup required. Touch Screen Interface: Capacitive touch display presents tank-side inventory information and simplifies configuration of communications and connected devices. Hazardous Area Approved: Explosion-proof and flameproof certifications for use in Class I, Division 1 and Zone 1 environments. Multiple Communication Protocols: Supports MODBUS®, Mark/Space, Biphase Mark, and L&J Tankway for flexible system integration. Ancillary Device Integration: Supports up to four HART devices, RTD temperature inputs, and multiple analog and digital I/O options. Drop-In Gauge Compatibility: Mounts directly to most mechanical tank gauges including Varec, GSI, L&J, and Sakura. Automation Ready: Enables control of alarms, relays, pumps, and valves through software-driven contact outputs and limit switches.
