Tel-Tru P421 Level Sensor
Tel-Tru® type P421 pressure level sensors are designed for the OEM and end-users where continuous submersion in sludge/slurry applications is required. Their key feature is the clog free design of the sensing diaphragm, which improves reliability and lowers maintenance. An internal network of MOVs and dual gas discharge tubes protect against lightning, while dual sealing techniques ensure the integrity of the waterproof seal. The all welded sensing diaphragm is backed up with a solid piece of stainless steel and can withstand the most abrasive/cyclical applications.
