133 STDT

SBEM’s Automatic Tank Level Gauge 133 STDT (Smart Tank Data Transmitter) is a robust, microprocessor-based device engineered for accurate digital conversion and transmitting product level and temperature data in large industrial storage tanks. Designed to integrate with SBEM’s float and tape-type ATLG or retrofit with other makes using suitable adaptors, the 133 STDT ensures precision measurement with ±1 mm level and ±0.2°C temperature accuracy. It utilizes spot or multi-point Pt-100 temperature sensors and transmits data via a two-wire RS485 bus, allowing up to 16 transmitters on a single cable. This intelligent transmitter features RS-232C output for tank side indicators and is housed in a flameproof enclosure with intrinsically safe terminals. The built-in diagnostics and self-checking microcontroller ensure reliable field performance, while optional displays provide sequential readings of level, temperature, and alarm status. Ideal for global tank inventory management systems, the 133 STDT ensures secure, centralized data access and reduced cabling infrastructure.
