10/300# 135 OHM PROP.#-TROL
The Honeywell L91A1136 Proportional Pressuretrol Controller operates single stage gas and oil burner systems. The controller is factory preset for 10#/300# burners and features a 10-300 psi inlet control range for operation of natural or LP gas control valves. The pressuretrol controller uses a unique sensor which allows the precise match of controller output to the pressure and flow characteristics of the burner or fuel flow device. Operates 115 Vac, Control signal/relay contacts rated at 1 amp @ 28Vdc, is for use with standard stem type valves or Micro-Pilot valves where connections
Honeywell's Proportional Pressuretrols are used for system control by providing proportional pneumatic output at pressures ranging from 10 psi to 300 psi.
The L91A1136 Proportional Pressuretrol Controller has been specifically designed for low pressure processes, and therefore it is ideal for use in watersoftening for both residential and commercial applications. It uses a dual-range design with a differential pressure orifice to sense very low pressures in excess of 10 psi (single range) and very high pressures up to 300 psi (dual range).It requires only 3 pipe connections, two differential pressure orifices, and a check valve which makes it suitable for a wide variety of control applications. The controller is packaged in a thermoplastic housing that is easy to handle
This proportional pressuretrol controller is used to control process equipment in the medical, beverage and food processing industries. This product senses fluid pressure and modulates an output flow featuring a "proportion-to" function that controls a variable speed vane regulator. It cycles on and off as needed and turns the unit off when there is no pressure.
The L91A1136 10 – 300 Psi proportional pressuretrol is designed for maintaining constant control of pressure in closed systems. Less used than the 1135 but also preferred by many process industries. The key feature being the ability to adjust differential pressure of approx. 0 – 32 psi (7 bar)
The Model 91A1136 proportional pressuretrol controller controls one or two resistive type heating, ventilating and air conditioning (HVAC) systems. The unit automatically turns a system on and off to maintain a constant temperature in the conditioned space in response to changes in the supply air temperature.
A low cost proportional pressure controller with 10" NPT port, -10 to 500 PSI. 0-100% output ratio (25-625 PSI) 0.1% of span (10psi/500psi). 6.3 to25VDC input. BF bypass. Built in safety relief valve, manual reset only.
