PR 7501 Ex Temperature Transmitter, Field-Mounted, HART Protocol

• 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 the PR guided menu.
• PReset and HART modem.

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 the 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.
