NOSHOK 800-1-8-10A-3-ST8 Electronic Indicating Pressure Transmitter/Switch

The NOSHOK 800-2-2-14.5/100-2-ST8 is an electronic indicating pressure transmitter and switch. It has a compound range of −14.5 to 100 psig, one programmable switch output and a 4–20 mA analog output. It connects through a 1/4″ NPT male port and an M12 x 1 4-pin connector, and includes a 0.8 mm stainless steel threaded orifice.

Part number breakdown:

• 800: series
• 2: one switch with 4–20 mA analog output
• 2: 1/4″ NPT male
• 14.5/100: −14.5 to 100 psig
• 2: M12 x 1 (4-pin)
• ST8: stainless threaded orifice

This model differs from the other 800 units in this group in two ways:

It adds an analog output. The 4–20 mA signal sends continuous pressure to a PLC or recorder, while the switch handles a local alarm or interlock. One device does the job of a transmitter, a pressure switch and a gauge.

It covers a compound range. The −14.5 to 100 psig span reads vacuum and positive pressure on one instrument, which suits pump suctions, vacuum-assisted processes, pneumatic systems and vessels that are evacuated and then pressurized.

The analog span can be rescaled between programmable low and high points. The span must be at least 20% of the adjustment range. The switch is configurable as NO/NC and PNP/NPN, rated at 0.5 A.

The ST8 orifice damps pulsation. The 1/4″ NPT connection suits standard instrument fittings. The 4-digit LED display, together with the rotating display and connector, makes the unit easy to read and wire.
