P221 Flush Diaphragm Pressure Transmitter
Brand: Tel-Tru Manufacturing Co.Key feature of the P221 is its non oil –filled sensing element. The sensing diaphragm is machined from a solid piece of steel, and can withstand the most abrasive / cyclical applications.
No thin diaphragm to break, to oil or to leak.
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.
