Honeywell Oil Pressuretrol Limit Controller - L404T1055/U

The Honeywell Oil Pressuretrol Limit Controller operates in the range of 5 to 50 psi, equipped with a Single Pole Single Throw (SPST) snap action function that breaks the circuit on pressure rise. The user-friendly design incorporates an automatic recycle switch operation and a simple 1/4 in. NPT mounting mechanism.

One key feature of the controller is the transparent plastic cover, which enables direct observation of the pressure settings. Tailored to accommodate high-pressure limits, this device is capable of breaking a circuit whenever the oil pressure rises beyond a predetermined setpoint. Adjustments for this controller are straightforward, precisely made through screws located on the upper side of the case.

Designed for versatility, the Controller offers dual mounting options. It can utilize 1/4 in. -18 NPT internal pipe threads or can be surface-mounted directly through the base of the case. A ground screw terminal ensures secure and proper electrical connections.

The Pressuretrol Limit Controller has an application scope including the function of an oil pressure limit switch for fuel oil, inclusive of rigorous heavy oil applications. Its electrical connections feature screw terminals, while the differential type is subtractive. Composed with a stainless steel diaphragm, the sensor element is guaranteed to be robust and durable.

In terms of operating conditions, the controller can optimally function in a temperature range of -35 F to 150 F (-37 C to 66 C), thus providing dependable performance in varied environmental conditions. The Honeywell Oil Pressuretrol Limit Controller amalgamates robust design with reliable functionality, promising a superior control solution for industrial automation.
