The Model 130 is available in Aluminum, Brass and 316SSbodies only with one or two hermetically sealed reed switch-es for low and/or high limit alarm.These CSA listed switchesare single-pole, double-throw, and may be connected to openor close on rising or falling pressure.Switching may be adjusted from 10% to 90% of the differen-tial pressure range of the instrument.Switches are enclosed in a weather resistant housing.Switchsetting is readily made with a screw adjustment.

A flexible elastomer diaphragm and calibrated spring sensedifferential pressure.The diaphragm provides total separationof the high and low pressure liquids and gases.Totally sup-ported at full travel in either direction, this feature assures fulloverrange protection to the rated working pressure of thegauge.A magnetic coupling transmits the sensing element motion tothe indicating pointer while assuring total isolation of theprocess fluid within the pressure capsule.This prohibits thepossibility of process fluid leaking into the gauge case.The few internal metal parts are 316 Stainless Steel, orHastelloy C as an option.The low range capability of the Model 130 is ideally suited forflow, liquid level and vacuum applications.

• Working pressure of 300 P.S.I.G.(20 bar) with apolysulfone body, and 500 P.S.I.G.(34 bar) in aluminum, brass, 316 S.S., and Hastelloy C.
• Over-range protection to rated working pressure.
• Either linear or square root (for flow) dials.
• Magnetic coupling between the sensing elementand the indicating pointer provides for complete isolation of the process fluid within the pressure capsule.
• Suitable for use on virtually all reasonably clean liquids or gases.
• Diaphragm design allows use of dissimilar fluidson high and low side of gauge.
• Can be used with vacuum or pressure applications.
• Ideal for liquid level indication for pressurized tanks.
• Wide range of elastomers.
• CE marked switches and enclosures are available.
• Five Year Limited Warranty
