Druck PTX 651 Process Pressure Transmitters Ranges: 1.5 psi (100 mbar) through 10,000 psi (700 bar) gauge or absolute Accuracy: ± 0.08% full scale (FS), best fit straight line (BSL) Stability: 0.1% FS per year Thermal effects: 0.005%/°F (±0.009%/°C) Reliability: MTBF of 100 years NACE compatible High proof and containment pressures Certified intrinsically safe RFI protectedThe PTX 651 and PTX 671 process transmitters combine micromachined silicon sensor technology with a fully welded stainless steel/Hastelloy construction to provide a high accuracy, stable, rugged pressure transmitter. These materials and environmental protection are ideal for arduous applications such as offshore and petrochemical.By incorporating technology developed for demanding aerospace and military applications, the PTX 651/PTX 671 provide excellent long term stability and feature minimal output noise, non-linearity and hysteresis.Process connections have been standardized as 1/2 NPT with a choice of electrical connections, either 3/4 NPT female conduit or junction box.Each transmitter incorporates RFI/EMC spike protection and is certified intrinsically safe.Within the junction box is a quick disconnect feature which negates the need to remove heavy duty cables when changing transmitters.
