The HMT370EX transmitter body has 2 lead-throughs (M20x1.5) for wiring. The combination of cable glands, conduit fittings, and plugs used in the lead-throughs is application-specific, and must be determined by the customer. For information on lead-through accessories available from Vaisala and lead-through accessory requirements, see Cable gland and conduit options.
CAUTION If you use lead-through accessories not ordered from Vaisala, note the following requirements:
  • The cable glands and cables used for wiring the device must not impair the Ex protection.
  • Unused lead-throughs must be sealed using Ex compliant plugs.
  • The glands and plugs must be water and dust tight.
Install the application-specific lead-through accessories and lead the wiring cables through them into the transmitter body: an example is shown below.
