CAL-C210 Recording Temperature Level Transmitter: High-Precision Monitoring for Industrial Efficiency

CAL-C210 recording temperature level transmitter is a smart recording temperature level transmitter designed for liquid level monitoring in challenging industrial environments. By integrating precision sensing with internal data logging capabilities, it serves as a robust solution for remote tank monitoring, water treatment, and chemical processing.

High Precision and Reliability CAL-C210 recording temperature level transmitter is with full digital compensation technology. By digitally correcting both linearity and temperature errors, the sensor maintains exceptional accuracy even in fluctuating thermal conditions. 304/316L stainless steel housing and multi-layer O-ring seals ensure an IP68 waterproof rating, providing long-term durability against corrosive fluids.

Ultra-Low Power for Remote Deployment Engineered for longevity, CAL-C210 recording temperature level transmitter is powered by a high-capacity 3.6V/2400mAh lithium battery. With an ultra-low standby current of less than 30μA, it supports extended data acquisition periods without the need for external power, making it ideal for isolated IoT applications.

Smart Data Management Users benefit from ultimate flexibility with customizable recording intervals ranging from 1 second to 255 hours. Integration is seamless via the RS485 bus protocol, allowing operators to wake up the transmitter remotely to configure settings or retrieve real-time pressure and temperature data.

Whether you are managing oil storage or municipal water systems, CAL-C210 recording temperature level transmitter delivers the reliability, intelligence, and precision required for modern industrial automation.

Application

Marine & Hydrological Surveys: Ideal for high-precision level and temperature measurement in oceans and rivers, ensuring continuous data recording for environmental research;

Water Conservancy & Reservoir Management: Provides reliable monitoring for dams and irrigation systems, offering years of unattended operation in remote locations;

Urban Flood Control & Drainage: A critical component for smart city flood warning systems, tracking water level changes in real-time during extreme weather events;

Municipal & Domestic Water Supply: Ensures stable monitoring of water towers and distribution tanks with no external power required, reducing infrastructure costs;

Remote Groundwater & Well Monitoring: Specifically designed for isolated wells where grid power is unavailable, providing 100% data traceability via internal logging.
