The Tel-Tru P121 is a precision grade threaded pressure transmitter with NEMA 4X housing for harsh environments. It is designed to last in high cyclical environments with or without the presence of waterhammering or spiking. Advanced manufacturing techniques, extreme environmental burn-in and thorough residual stress relieving procedures ensure the P121 maintains its performance over time.

The P121 is available in ranges from vacuum to 15,000 psi and is accurate up to ±0.10% of calibrated span. A wide range of outputs, process connections and electrical connections allow customers to tailor the instrument to the exact needs of their application. The rugged, 316L stainless steel construction features an all welded sensing element isolating it from induced stresses such as mounting torque, thermal excursions, and vibration and shock.

Applications for the Tel-Tru P121 pressure transmitter:

  • Hydraulics and pneumatics
  • Injection molding machines
  • Laboratory and test equipment
  • Marine and offshore
  • Petrochemical
  • Pumps and compressors
