Application

AMOT Model 4229/4429 Pneumatic Indicator is used as an accessory to provide a quick and reliable, visual indication of the status of a pneumatic system. The unit shows a black or red display in the non-pressurized condition and is designed to be panel mounted. The large 5/8" diameter ³Pressure On² display is visible when pressure is applied. The high contrast between the flat black or red ³At Rest² condition and the ³Pressure On² display is abrupt and unmistakable. The pins which comprise the display are visible for 180° around the unit and may be ordered yellow, white, green, or red.

Operation

In the non-pressurized condition, the array of nineteen indicator pins is concealed within the matrix of the pin guide. When the minimum operating pressure is applied to the port, the pins extend through the matrix. They will remain in the forward visible condition until the pressure is removed. It is satisfactory for use with clean, dry air or gas in systems with pressures from 20 to 150 psi.

The Indicator does not consume air or gas in either condition. It is non-electric and inherently explosion-proof. The Indicator offers an inexpensive, highly effective means of displaying the status of pneumatic components in a system.

AMOT designs and tests all products to ensure that high quality standards are met. This product should last for many years. For good product life, carefully follow AMOT's instal-lation and maintenance instructions; failure to do so could result in damage to the equipment being protected.
