Honeywell Proportional Pressuretrol Controller - L91A1052/U

The Honeywell Proportional Pressuretrol Controller is versatile and capable, designed to operate within a pressure range of 5 to 150 psi. This controller features a modulating switch operation that's regulated by a single potentiometer and delivers a modulating output of 140 ohms. The optional surface-mounting through the back of the case offers added flexibility during installation.

Designed with durability in mind, it is compatible for use with steam, air, noncombustible gases, and other fluids that are non-corrosive to the brass or phos-bronze bellows. It should be noted that it is not suitable for use with combustible mediums or any medium that could chemically harm the phos-bronze bellows (as seen in the 10-300 psi models) or the brass bellows (found in all other pressure range models).

The controller serves as a modulating pressure control for the regulation of liquids, air, or other non-corrosive gases. The controller's electrical connections are managed by screw terminals, ensuring secure and reliable connections. The sensor element of the controller features brass bellows. For optimal performance, the operating conditions should range from 32 F to 150 F (0 C to 66 C). This ensures consistent operation in various climates and ambient temperatures.
