The Tel-Tru P221 is a precision grade "non-filled" flush diaphragm sensor can withstand the most abrasive / cyclical applications. It is designed for the OEM and end user where ruggedness, high performance, and reliability are required at a competitive price. The key feature of the P221 is its non oil-filled sensing element. The sensing diaphragm is machined from a solid piece of steel meaning there is no thin diaphragm to break, to oil or to leak.

The P221 is available in ranges from 0-100 to 0-7500 psi and is accurate up to ±0.25% of calibrated span. A wide range of outputs and electrical connections allow customers to tailor the instrument to the exact needs of their application. The P221 is designed to last in high cyclical environments with or without the presence of water-hammering or spiking. Advanced manufacturing techniques, extreme environmental burn-in and thorough residual stress relieving procedures ensure the P221 maintains its performance over time. The P221 is designed to meet or exceed the standards for IS. FM/CSA approvals are pending.
