Honeywell Vaporstat Controller - L408J1025/U

The Honeywell Vaporstat Controller is a sophisticated and efficient device featuring an operational range of 0 to 16 oz/in2. Its function is to close a circuit based on pressure rise and it employs an automatic recycle switch operation mechanism. Designed for a 1/4 inch NPT mount, this controller is compliant even when wired incorrectly, enhancing its safety and reliability.

The device includes a high-quality stainless-steel diaphragm, making it suitable for use with various substances including liquids, air, noncombustible gases, ammonia, oxygen, distilled water, and similar media. Its SPDT switching capacity enhances its flexibility and functionality.

A unique feature of this controller is its clear plastic cover, allowing users to visually monitor pressure settings. The Vaporstat Controller can be mounted using a hexagonal fitting with 1/4 inch NPT internal threads, facilitating direct mounting to the 14026 (Steel) or 50024585-001 (Brass) steam trap (siphon loop). Moreover, it features a ground screw terminal providing additional security and convenience.

The controller's key application is to offer operating control and automatic limit protection for pressure systems, specifically those with pressures up to 4 psi. It achieves this through its electrical connections to screw terminals and a stainless-steel diaphragm sensor element, providing high responsiveness and accuracy.

In terms of operating conditions, the Vaporstat Controller functions effectively within a wide range, from -35 F to 150 F (-37 C to 66 C), showcasing its versatility and resilience in diverse environments. This underscores its suitability for most industrial automation and control applications.
