P121 Threaded Pressure Transmitter
Brand: Tel-Tru Manufacturing Co.The P121 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 P121 maintains its performance over time.
Every Tel-Tru P121 is rated to NEMA 4X standards regardless of the output (mVdc, Vdc, or mAdc) or pressure format (gauge, absolute, or vacuum).
Pressure ranges are available from psig: 0 to 3 (kPa: 0 to 20.68, bar: 0 to 0.2) through psig: 0 to 15,000 (kPa: 0 to 103,400, bar: 0 to 1,034).
