The 805 pressure switch-transmitter is a compact loop-powered pressure switch-transmitter. A supplemental continuous output is also available (either 4-20mA or 1-5VDC). Its rugged construction makes cost of ownership low and it carries a three-year warranty. The SOR® 805 pressure switch-transmitter is suitable for hazardous locations and hostile environments where space is limited. It meets applications where low-cost, discrete and continuous monitoring is preferred. Switch set points and supplemental continuous output zero and span points are field adjusted via SOR Calibration Kit with USB communication cable.

The primary switch output of the 805QS is a “Normally Open Solid State Relay” rated 30V, 120mA. It can be configured 3 ways; as shown below. Switch set point(s) and supplemental continuous output zero and span points are set at the factory as specified by the customer. In all three configurations, the fail-safe state for the 805QS switch output will be open (i.e., if power is removed from the 805QS, the switch contacts will open automatically).
Window Mode Switch is closed when the process pressure is within the user selected range (LO and HI set points), and open when the pressure is above or below that range.
Close on Rise/Open on Fall Switch is open when the process pressure is below the user selected set point and closed when the pressure is above that set point.
Open on Rise/Close on Fall Switch is closed when the process pressure is below the user selected set point and open when the pressure is above that set point.

|Description||Stainless Steel, 1/2”NPT(M) with 1/4”NPT(F), Process Connection (316SS for ranges -100 si and below) (17-4SS for ranges above 0-100 psi)||316SS, 1/2” NPT(M) flush-mount, liquid filled, diaphragm seal, Process Connection||17-4SS, Autoclave F250C Female (For 1/4”OD Tubing), Process Connection||If alternate process connection is required, please consult the factory|
|Application||General applications with process materials not containing heavy particulates that could induce clogging of pressure port.||Use when applications contain dirty, sticky or high particulate process material such as paraffin.||Use for applications where pressures are greater than 10,000 psi, Standard NPT threads re not suitable at these high pressures.||SOR can provide many other process connections including:|
• Thread & port size adapters
• Direct & remote mount diaphragm seals
• Tri-clamp/sanitary fittings
LCD Display “IN” Option
The “IN” LCD display is a low cost option for when a simple local indication is needed. The “IN” option is provided with a 5-digit backlit loop powered LCD display enclosed in an explosion roof housing with terminal block connections inside. For configuring the display, push buttons are provided on the front of the housing. Configuration of the display and transmitter are done separately.
