      1540 Side Mounted – Non-Bleed Pneumatic Level Switch

      1540 Side Mounted Pneumatic compact Level Switch

      compact Models: 1540
      Ranges: vac to 1500 psi, vac to 100 bar; -40° to 400°F, -40° to 204°C Maximum process pressure 60 SCFH (1.7 CMH)
      Certifications: Unit: RTN
      Warranty: 5 Years

      The 1540 is a side mounted, float-operated, non-bleed pneumatic 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. The float arm moves a magnet which in turn moves a shuttle that either blocks or allows pilot pressure to pass and operate ancillary equipment. A manual check option allows you to verify switch integrity without removing the unit from the vessel.

      • Maximum process pressure – 1500 psi (103 bar)
      • Suitable for air or any dry or filtered gas
      • Manual check option

      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
