Field mounted HART temperature transmitter 7501 – RTD, TC, Ohm, and bipolar mV input and analog output – High definition local operator interface (LOI) with 3 optical buttons – Selectable red or white backlight – Ex d explosion proof / flame proof in aluminum or 316 stainless steel version – HART 7 functionality with HART 5 compatibility High defintion display • 0, 90, 180, & 270 degree position adjustments. • Monitoring, programming and diagnostics view. • Extensive diagnostics with flashing red or white backlight • Supports 7 languages. Local operator interface (LOI) • 3 optical buttons; up, down and enter. • Dynamically adaptive to wear or accumulation of dirt. • Immune to interference from ambient light sources. • Useable with or without gloves. Configuration • From the LOI through PR guided menu. • PReset and HART modem. • HHC, DCS or AMS via HART. Mounting / installation • For installation in zone 0, 1, 2 and zone 20, 21, 22 and in Class 1, Division 1 and 2 applications. • Hardware assessed for use in SIL applications. • Mounting on 1.5”–2” pipe bracket or on wall / bulkhead. Application • Linearized temperature measurement with TC and RTD sensors e.g. Pt100 and Ni100. • HART communication and 4...20 mA analog PV output for individual, difference or average temperature measurement of up to two RTD or TC input sensors. • Conversion of linear resistance to a standard analog current signal, e.g from valves or Ohmic level sensors. • Amplification of bipolar mV signals to standard 4...20 mA current signals. • Up to 63 transmitters (HART 7) can be connected in a multidrop communication setup. Technical characteristics • NAMUR NE43 and NE89. • HART protocol revision can be changed by user configuration to either HART 5 or HART 7 protocol.
