Overview
The Rosemount 0400-13 Endurance Conductivity Sensor is a ruggedized contacting conductivity instrument designed for accurate, real-time measurement of electrolytic conductivity in clean, non-corrosive liquids. The sensor measures electrolytic conductivity in applications from high purity water to clean cooling water. This model is capable of withstanding a maximum temperature of 221°F/105°C and a maximum pressure of 250 PSIG/1825 kPa.
Key Features
- Factory Pre-Calibrated: Factory-measured cell constant ensures out-of-the-box accuracy and no initial calibration requirements.
- Durable Construction: Electrodes are titanium; body is 316 stainless steel; insulator is PEEK; O-rings are EPDM.
- Pt1000 Thermocompensation: Designed with an RTD Pt1000 sensor for precise and repeatable conductivity measurements.
- Ideal Range: Ideal for use in clean, non-corrosive liquid having conductivity less than 20,000 µS/cm.
- Compact & Lightweight: Weighing only 480 grams, the sensor is lightweight and easy to install.
