The Model PT combines micro-machined silicon diaphragms with fully welded stainless steel pressure ports to provide a highly accurate, stable pressure transmitter. It is constructed with the materials and environmental protection required for industrial applications. The silicon sensors incorporate developments derived from aerospace applications. These developments are used to decrease output noise, non-linearity, and hysteresis and to improve long-term stability. A detachable industrial electrical connector provides access to independent zero and span controls. Each transmitter incorporates RFI/EMC and electrical spike protection. Features * Process pressure range: 1.5 to 1,000 psi (0.1 to 69 bar) * Accuracy of ± 0.25% of full scale * Process temperature range: -40 to 250 °F (-40 to 121°C) * 2-wire, 4 to 20 mA output * CE and FM approved
