Kingmach Temperature and Humidity Acquisition Module
When monitoring humidity in a railway tunnel, a half-degree error can mask early signs of condensation. Kingmach’s Temperature and Humidity Acquisition Module is built for jobs like that—not just labs. It uses industrial-grade capacitive sensors and 24-bit ADC, avoiding the drift common in cheaper resistive types. The module outputs digital signals directly, so you can hook it into a PLC or wireless gateway without extra converters. Field tests show stable readings from -40°C to 85°C, with humidity tracking tight between 0 and 100% RH. For long-term geotechnical installations, the epoxy-potted circuitry and IP67 housing keep moisture out even in saturated soils. Kingmach also pre-calibrates each unit and stores calibration constants onboard, which saves setup time when you replace a sensor in the field. Unlike generic data loggers, this module is designed to integrate into larger monitoring networks—it supports Modbus RTU and can be daisy-chained with other sensors. If your project requires specific cable lengths or mounting brackets, custom orders are handled directly by the engineering team.
Technical Detail
This acquisition module translates physical temperature and humidity into data your monitoring software can actually use. It is built around a Swiss-made sensor element and a 32-bit MCU that handles signal processing and protocol conversion on the same board. Power consumption stays under 10 mA during measurement, so a small solar panel and battery can keep it running for years in remote landslide sites. The aluminum alloy enclosure with a sintered filter protects the sensor from dust and water spray while allowing air exchange—important for fast humidity response. On the communication side, you get RS485 with Modbus RTU as standard; analog 4–20 mA outputs are available on request. Multiple units can be connected on a single bus using screw terminals, eliminating the need for junction boxes in distributed arrays. Kingmach ships every module with a signed calibration certificate traceable to national standards, and we store the calibration coefficients inside the module’s memory. This means any data logger or SCADA system that reads the Modbus registers automatically gets compensated values, no manual entry. For projects requiring hundreds of nodes, Kingmach’s global distribution and local technical support keep lead times short—usually 4 weeks for standard configurations, with faster turnaround for rush orders through our regional partners. Because we manufacture in-house, we can also adjust filter housings, cable glands, or output scaling to match your specific geotechnical application, whether it’s concrete curing, slope stability, or dam seepage monitoring.

FAQ
The standard housing is IP67 with a sintered filter that blocks dust and liquid ingress while permitting air flow. For submersion or extremely high humidity, we can provide customized sealing and coating options.
Each module ships with a factory calibration certificate and stores coefficients onboard for automatic compensation. Under normal field conditions, annual recalibration is recommended, but many installations show stable performance for two years in mild environments.
Yes. The module has RS485 output with Modbus RTU as standard. If your logger supports Modbus, just wire the bus and read registers. 4–20 mA analog output is also available as an option.
Absolutely. We handle custom cable lengths, connector types, and even firmware tweaks. Contact our engineering team with your specifications—we typically quote within a few business days.
Under 10 mA during measurement, dropping below 1 mA in standby. This makes it well-suited for solar-powered remote stations; a small panel and rechargeable battery can sustain continuous operation for years.
