The ALCO PS3 is a Pressure Switch with fixed switch-point settings.

Features

•Maximum Operating Pressure up to 43 bar

•Test Pressure up to 48 bar

•Standard factory settings from stock in small volumes

•High and low pressure switches

•High temperature version with snubber for direct compressor mounting (Range 6)

•Direct mounting reduces the number of joints and thus avoiding potential leakage

•Precise setting and repeatability

•IP 65 protection if used with the new PS3-Nxx and PS3- Lxx cables with plug (acc. EN 175301-803), no additional gasket required (molded into plug)

•Customer specific versions in multipacks, minimum order quantity 100 Stück

Options

•For direct mounting on a pressure connection (free standing) or with a capillary tube

•Direct compressor head mounting with high temperature bellows and snubber:

-reduces the number of joints

-avoids potential leakage

-saves high cost of flexible hose

•TÜV approved versions for high and low pressure

•Micro-switch for narrow pressure differentials

•Gold plated contacts for low voltage/current applications

•Cables with plug PS3-Nxx/PS3-Lxx not included; to be ordered separately (see page 8 for details)

Introduction

PS3 are equipped with a SPDT snap action contact, switching from 1-2 to 1-4 on rising pressure and from 1-4 to 1-2 on falling pressure (see diagram). The PS3 is factory preset according to customers specification and is not adjustable. Several models are available:

•Low pressure switch, with automatic or manual reset

•High pressure switch, with automatic or manual reset

•TÜV approved safety high pressure limiter with automatic reset

•TÜV approved safety high pressure cut-out, with internal or external manual reset

TÜV approval for pressure switches can be reached either by using a double diaphragm (Pressure range 1-5) which acts in a fail-safe mode or by a single pressure element (Bellows, Pressure range 6) which is able to resists to > 2 Mio. cycles between 50% and 100% of the maximum operating pressure (see 4.6.1 of EN 12263).
