The Type 03 absolute sensor measures pH. The sensor has rugged enamel Glasteel™ construction with an integral temperature sensor. Users can mount the sensor directly into the process, in any orientation, thus sensing the pH directly and without a protective cage. The sensor has insertion depths of up to 10 ft and ATEX approval.

The Type 03 pressurized reference system eliminates inaccuracy and drift caused by junction potential diffusion or poisoning. The result is a more stable measurement leading to more effective and accurate process control. The wear-resistant smooth enamel finish uses the product flow to keep the surface of the sensors clean while resisting any potential product buildup.

Single point calibration in the process further minimizes maintenance. Operators do not need to remove the sensor for calibration. Additionally, users can leave the sensor dry in an empty pipe or vessel without causing permanent damage to the sensing elements.

The Type 03 is suitable for use with the Protos and Stratos Multi, Pro, and Evo transmitters.

Robust Glasteel Sensor

• Resistant to most corrosive substances, even under extreme thermal conditions
• Essentially inert, so it cannot adversely affect product purity or flavor
• Resists the buildup of viscous or sticky products, leading to better heat transfer, less frequent cleaning, and higher performance
• Strong: fusing glass to steel produces high strength, corrosive resistant composite

Applications for the Type 03

A Type 03 pH sensor is the ideal sensor for processes where:

• Glass sensors are being replaced frequently
• Batch processes dry out sensors during empty stages
• Media contains heavy and abrasive suspended solids
• Long insertion depths are required
