Applications
Triple approval (UL, cUL and ATEX) mean the 12 Series meets the demanding requirements of critical applications within hazardous locations. Additionally, the 12 Series complies with ANSI/ISA 12.27.01, "secondary seal requirements for process sealing between electrical systems and f lammable or combustible process fluids." It can be used in a variety of applications where space is at a premium. All metal wetted parts comply with NACE MR-0175 and the 316 stainless steel, type 4X enclosure rating assure long-term performance in the harshest environments.
 
Technology
At the heart of the 12 Series is a Belleville spring assembly. The spring is a small conical washer that transfers motion to a hermetically sealed 1 or 5 amp microswitch. Its ‘snap-action’ provides fast, positive contact transfer. The Belleville spring ‘snaps over’ when pressure is applied and ‘snaps back’ upon pressure release.
