Sensocon A1 Series Installation And Operation Manual

Series A1 / A2
– Installation and Operation Manual

1. INTRODUCTION

The series A1 and A2 are microprocessor based digital pressure gauges for
positive, negative, and differential measurement designed to be a direct
replacement for mechanical gauges. The ½" LCD display gives the gauge
improved readability and precision. These products also feature 5 user
selectable engineering units including in. w.c., mm w.c., cm w.c., kPa, and
Pa. The A2 series adds a "process arch" which gives the gauge a similar
look to mechanical gauges by giving a continuous percent output status.

2.1 Mounting

Flush Mounting – For new applications, cut a 4
Insert the control with the provided gasket through the hole and secure it to
the panel with the provided mounting tabs and screws. Retrofitting old
technology is also easy with the Series A1 and A2. They have been
designed to fit in industry standard holes ranging from 4
simply remove the old device and insert the new control into the existing
cut out.
Surface Mounting – Surface mounting the Series A1 or A2 requires the
optional weather proof cover. Once the control is wired and the weather
proof cover has been attached, the control can be mounted to any flat
surface with the four mounting screws provided with the cover.
Flush Mounting with Weather Proof cover – The Series A1 and A2 can also
be flush mounted with a weather proof cover. The procedure is the same as
above, but utilizes two extra long mounting screws (provided with the
weather proof cover) for the bottom two panel connections.
