INTRODUCTION

The PT-AMR is a magnetically operated bi-stable reed switch, operated by the magnet in the

flowmeter’s float. The limit switch can be supplied as a normally open switch when the float is

below the switch (PT-AMR NA), or as a normally closed switch (PT-AMR NC).

ELECTRICAL CONNECTION

For the electrical installation, a multi-conductor cable should be used to obtain a good seal with

the cable gland. The connector is provided with a PG 9 cable gland, suitable for a 4.5 to 7 mm

outside diameter cable. Terminals 1 and 2 of the connector are connected to the two ends of the

reed switch.
