This sensor holder with front end 1 1/4 inch threaded fitting is ideal for high pressure or aggressive applications where the sensor requires extra protection. This fitting allows the sensor to be firmly bolted into place using the hex flats on the threaded fitting without damaging the sensor. It allows maximum torque to be applied to the threaded connection to ensure a secure fitment in the process line. It also provides additional sensor protection, both externally and inline and is recommended for applications with pressure greater than 100 psi to improve safety.
The challenge The high-pressure acid leach process at this nickel-cobalt plant was destroying pH sensors. The initial problems were so severe that it made it near impossible to control the process.
