    6.3. Casing and Electrical Connections 6.3.1. The casing of the PYRP-28 and PYRD-28 transmitters is manufactured from ø27 tube (304 st steel or 316 st. steel), fixed to the the sensing module as shown in figure 1b and 7. At the electrical connection end is the PD type electrical connector with PG-11 packing gland.

    (less than -25°C), the transmitter and impulse lines should be heated. 7.3. High Process Temperatures. The PYRP-28 and PYRD-28 transmitters may be used to measure media with temperatures of up to 120°C. To protect the sensing module from temperatures in excess of 120ºC, suitably long impulse lines should be incorporated to disperse the heat and to reduce the process temperature at the transmitter inlet.

    9.4. Connections for transmitters incorporating terminal housing (PZ Type) The PYRP-28 and PYRD-28 transmitters with PZ terminal housing should be wired to the terminal block as shown in figure 2 (page 15). Tighten the packing gland ensuring there is a water tight seal on the cable, and refit the screwed terminal cover and gasket.
