Detcon PI-700 VOC Sensor
The Detcon PI-700 by Teledyne is a non-intrusive “Smart” sensor that uses photo-ionisation detector technology to monitor VOC gases over ranges from 0-10 ppm to 0-5,000 ppm. The PI-700 are the low-range models, and the PI-701 are the high-range versions. In the sensor design, Detcon has successfully converted the sensitive laboratory-style PID technology into a rugged, environmentally insensitive, and long-life industrial gas sensor. The plug-in, field-replaceable detector features oversized gold-plated connections that help prevent corrosion.
The PI-700’s rugged framework includes an electro-polished 316 stainless steel housing with fully encapsulated electronics and dual-layer surge protection. This innovative design virtually eliminates sensor failure due to water ingress, corrosion, vibration, and transient spikes. A primary feature of the Model PI-700 is embedded intuitive software that simplifies the operator interface by guiding the user through routine calibration, configuration, and fault diagnostic functions using a built-in alpha/numeric display.
The Model PI-700 is equipped with standard analogue 4-20mA and Modbus RS-485 outputs. Among its unique features is a wireless option that can be used with Detcon’s SmartWireless product line. Additional integration options include a Remote Alarm Module (RAM) and HART. Detcon’s PID sensors have a long shelf life and are supported by an industry-leading warranty.
Applications: Pharmaceutical industry, Power plants, Chemical industry, Air quality, Refineries and petrochemical plants, Solvent recovery systems, Wastewater treatment plants, Marine and offshore oil wells, Pulp and paper manufacturing, Painting and coating operations.
