N-E13DM Differential Pressure Transmitter

These transmitters measure differential pressure and transmit a proportional 4 to 20 or 10 to 50 mA dc signal. They are 2-wire transmitters that have been type-tested for applications under seismic, radiation, aging, and loss-of-cooling accident (LOCA) environments of Nuclear Power Plants per IEEE 323-1974 and 344-1975 requirements.

  • QUALIFIED FOR NUCLEAR APPLICATIONS
  • A Design Control and Quality Assurance Program has been established which complies with ANSI N45.2 and Code of Federal Regulations 10CFR50, Appendix B. Certificates of Testing are provided with each transmitter relating to nuclear cleaning, hydrostatic testing, and calibration. Production transmitters have been type-tested to demonstrate their performance, under typical accident conditions, for Class IE, in-containment applications of Nuclear Power Generating Stations. Type test reports (user documents) are available.
  • SERVICEABILITY
  • The complete line of N-E13 Series transmitters is supplied with detailed instructions and parts lists that provide the user considerable flexibility and capability for field repair.
  • FIELD INTERFACE
  • An optional junction box allows quick and easy field wiring to terminal blocks without the need for nuclear splices or seals. Optional seismic mounting brackets allow vertical or horizontal pipe mounting or wall mounting.
