1710 Compact Level Switch

1710 Compact compact Level Switch

Models: 1710
Ranges: vac to 1799 psi (124 bar) -40° to 700°F (371°C)
Certifications: Unit: ATEX, CSA (US and Canada), GOST, IEC, KOSHA, SIL
Warranty: 5 Years

The SOR 1710 is a direct mounted, horizontal, float-operated level switch suitable for plant and OEM applications where open or closed contacts are required to signal presence or absence of liquid at a discrete level. While the 1710 shares a lot in common with its cousin the 2210, the 1710 differs in a couple key features.

First, the 1710 is designed to handle hazardous environments. Worldwide Flameproof/Explosion proof listings are standard on each and every 1710. No additional cost, no additional accessory codes to remember.

Second, the 1710 can be ordered as a direct mounted device or with an optional chamber. This gives OEMs and plants the flexibility to mount the 1710 directly in the side of the vessel whenever possible, saving cost. The 1710 can also be supplied with a chamber providing most of the functionality of the 2210 but with hazardous location approvals.

SOR is once again pushing the boundaries of traditional technology providing more value than ever before.

  • Field proven design
  • Compact size
  • Direct mount or chambered versions available
  • Rated for process temperatures up to 800°F (427°C) and pressures up to 1500 psi (103 bar).
  • CSA (US and Canada) Explosion proof and ATEX/IEC Flameproof approvals on all units
