Temperature Compensation Module

Kingmach's temperature compensation module is purpose-built for long-term monitoring where ambient temperature changes can't be ignored. It sits between the sensor and the data acquisition system, and most units accept both vibrating wire and resistive sensor types. Inside, the module uses a precision thermistor or RTD to read local temperature, then applies a correction algorithm—typically a polynomial curve or a segmented lookup table stored in non-volatile memory. The corrected output is what your logger sees, but raw uncompensated data is often available on a secondary channel for auditing. From a specification standpoint, engineers usually expect a compensation range of -20°C to 80°C with stability around 0.1°C repeatability, and that's what this module delivers. Power draw is kept deliberately low—often under 1 mA in active mode—so it won't drain remote battery stations. An IP67-rated inline housing with screw terminals makes field wiring quick, and Kingmach stocks common connector variants or can integrate customer-specific connectors through their customization service. One thing that sets their approach apart is how they handle non-standard sensors. If you have an older inclinometer or a custom pressure cell with an unusual thermal curve, their engineering team can load a unique compensation profile before shipping. It saves you from building your own lookup logic in the datalogger or SCADA system. For project managers, the main payoff is fewer false positives in automated alarm thresholds and more confidence in settlement or water level trends that span seasons. Maintenance is minimal: a seal check every couple of years and verifying the compensation doesn't drift beyond your QA limits. In dense sensor arrays, the module's small footprint helps keep cable clutter manageable.
