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)

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

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).
