Water pH sensor SMARTPAT PH 1590

Potentiometric pH sensor for potable, process or treated water applications • 2-wire loop powered, 4…20 mA/HART® 7, for direct connection to a PCS • Process connection: 3⁄4 NPT (male) • 0…14 pH; Max. +80°C / +176°F • Glass sensor with ceramic diaphragm and Pt1000 for temperature compensation The SMARTPAT PH 1590 is a 2-wire loop powered pH sensor for general applications with treated water (e.g. potable or process water). Equipped with CPVC body material, large ceramic diaphragm and integrated Pt1000 for temperature compensation, the sensor fits various application requirements. It can be installed directly into a pipe or tank with the 3⁄4 NPT (male) process connection. Offline calibration of the sensor is possible under controlled conditions, generating cost savings due to less operator time on-site and longer sensor lifetime. The SMARTPAT PH 1590 is part of the SMARTPAT product family - the first sensor line in the market featuring an integrated transmitter with built-in fieldbus communication (HART® 7) and current output. The real open standard enables a direct connection from the sensor to the process control system. Unlike other commercially available pH sensors, there is no need for external transmitters. Thus, price and maintenance costs of the complete measuring point are considerably reduced. Product highlights • No external transmitter needed • Double junction for extended lifetime and wide application range • Offline calibration under controlled conditions: Cost savings due to less operator time on-site and longer sensor lifetime • Robust CPVC body material • With integrated Pt1000 and standard VP2 connector
