Supports 1-5 V Hydrostatic Level Sensors
The OleumTech® OTC Wireless Hydrostatic Level Transmitter is designed to accurately measure liquid levels by monitoring the pressure at the bottom of vented top-mount tanks, deep wells, water towers, rivers, and lakes. The WT-LL5 Level Transmitter features a 0-5 Vdc analog input and delivers high-resolution, 24-bit analog-to-digital conversion (ADC) for precise readings. It can supply up to 12 Vdc to connected sensors and offers flexibility by allowing users to choose their preferred sensor and mounting method. Additionally, the WT-LL5 includes a discrete input for added versatility. Powered by a replaceable battery pack, this ultra-low-power transmitter ensures long-lasting performance with a lifespan of up to 10 years. A convenient push-button LCD interface enables easy device configuration and provides immediate access to real-time process data.
Reliable, Scalable and Safe
The field-proven wireless transmitter seamlessly communicates with an assigned wireless gateway within the OTC Wireless Sensor and I/O Network, forming a highly scalable system that can accommodate virtually any I/O requirement.
The OleumTech Wireless Transmitter is certified for use in Class I, Division 1 (Zone 0) hazardous locations. It is intrinsically safe, designed not to cause a spark, and can be serviced without being removed from a process.
This product is also available without a local display.
