Relative pressure transmitter STD81

ceramicpiezoresistive4-20 mA

The STD81 features a piezoresistive ceramic sensor and a rotatable 5 digit LCD display that permits the user to visualize the variation of either the level or the pressure of the process by value, percentage or a real time graph. The STD series provides a 4…20mA analog signal with superimposed HART communications protocol, programmable Zero/Span adjustment, decimal point, damping and display mode parameters via three programmable buttons. Optional Accessories: TR202 Relay Digital readout + 2X active relays/ 1X F.S. Relay + passive 4…20mA out Application: Pressure and Level measurement for liquids, gases and vapor Operating Voltage: 9...45Vdc Consumption: Max. 22mA Output Signal: 4...20mA with HART Protocol Protection: Polarity Inversion / Power Surges Load: max= [(Vmax -15)/ 0.002A] Eletromagnetic Compatibility (EMC): Interference immunity & interference emission according to (GB/T17626.2-1998), compliance with IEC 61000-4-3:1995 Optional EX- protection: EEx ia IIC T4-CT6 Response Time: +/- 200 ms Body Material: 316S.S or Aluminum (both with Acrilic Window) Wetted Parts: 316 Stainless Steel Seal: Viton Sensor Material: Piezoresistive Ceramic Process Connections: BSP / NPT / Flange / Sanitary / SAE (others) Electrical Connections: M12 connector / Crimped w/ polyurethane vent tube cable Local Indicator: Display w/ backlight - rotatable 330°/ 5 digits / 7 segments / 8mm Range: -9.9.9.9...9.9.9.9.9 Units: Bar / mbar / % / m / cm/ Kg / Torr
