The Applications

1. Chemical Plant – Isolating pH and ORP Sensor Signals

In chemical production, sensitive pH and ORP probes often generate small, low-level signals that are vulnerable to electrical noise and potential differences. The MINI MCR-SL-UI-I-LP-NC isolates these signals and converts them into a reliable 4–20 mA output, allowing them to travel long distances without distortion. Its loop-powered design reduces the need for extra power wiring, which is especially valuable in classified zones where minimizing equipment is essential. By protecting controllers and ensuring accurate readings, the unit improves process safety and measurement reliability.

2. Water Treatment – Conditioning Flow Meter Outputs

Water treatment facilities rely on flow meters that commonly deliver weak current or millivolt signals. These must be converted into standardized levels for use in SCADA or PLC systems. The MINI MCR-SL-UI-I-LP-NC handles this task by filtering out surrounding interference from pumps and motors, ensuring the control system receives a stable signal. Its slim housing allows dense installation inside compact panels, which is a big advantage in control rooms with limited space. The fast response time helps operators react quickly to sudden changes in flow conditions.

3. Food Industry – Integrating Temperature and Pressure Sensors

Food processing equipment uses many analog sensors to monitor pressure and temperature under strict hygiene conditions. The MINI MCR-SL-UI-I-LP-NC provides isolation between these sensors and control units, protecting devices from ground loops while maintaining accurate measurement. Since it requires no external power supply, installation is simple and wiring is reduced, lowering the risk of contamination from additional cabling. Its durable design ensures reliable operation even in areas with frequent washdowns and fluctuating temperatures, supporting consistent product quality and compliance with industry standards.

4. HVAC in Large Buildings – Stabilizing Distributed Sensor Signals

Heating, ventilation, and air conditioning systems in high-rise buildings use sensors spread across multiple floors. Long cable runs often cause voltage drops and interference from other electrical equipment. The MINI MCR-SL-UI-I-LP-NC solves this by isolating and converting the raw signals near the sensor into a clean 4–20 mA current. This stable output can travel long distances without loss of accuracy. Because the module is compact and mounts directly on DIN rail, engineers can install many units in limited cabinet space, reducing downtime and simplifying system maintenance.
