P321 Sanitary Pressure Transmitter
Brand: Tel-Tru Manufacturing Co.Tel-Tru’s P321 Series is designed for the OEM and end user where ruggedness, high performance, and reliability are required. Key feature of the all welded sensing element is its isolation from induced stresses. This results in negligible zero and span offsets due to the installation clamping force effects. This product is modular and is configurable. The P321 is built using advanced manufacturing techniques, with automated welding procedures, extreme environmental burn-in and thorough residual stress relieving techniques. The P321 NEMA 4X packaging ensures reliable service in the wash-down environments of the sanitary industry regardless of signal output or pressure format. Every P321 sensing diaphragm is “backed-up” with a solid piece of stainless steel which greatly improves the resistance to sharp objects and overpressure.
