規格介紹:WIKA A2G-90
Differential pressure gauge with pressure switch
詳細介紹:
The model A2G-90 differential pressure gauge with pressure switch is a combination of the model A2G-05 differential pressure gauge Eco and the model A2G-40 differential pressure switch, which have been fitted within a compact plastic case.
The A2G-90 is ideally suited wherever an analogue indication (e.g. for local control) and a switching output (e.g. for direct connection to a higher-level controller) are required.
Features:
- • Compact indication instrument and pressure switch fitted within a plastic case
- • Single-pin microswitch (change-over contact)
- • Switch point adjustable when installed
- • All connections already preassembled

WIKA 230.15-851 Bourdon tube pressure gauge with switch contacts
The model 230.15 is a bourdon tube pressure gauge with up to 2 Reed contacts model 851. It was created for high purity applications that require discrete monitoring outputs for globally installed systems and life safety applications. The switch point can easily be adjusted by removing the window and putting the mark pointer on the desired value on the dial’s circumference. Features: • Up to 2 Reed contacts, SPDT • Switch points adjustable on site • Wetted parts from stainless steel 316L and face seal process connections • Electropolished internals and case, internal surface finish up to Ra < 0.25 μm [Ra < 10 μin] • Scale ranges from -30 inHg ... 45 psi to 0 ... 6,000 psi
WIKA PGS23.100, PGS23.160, PGS26.100, PGS26.160 Bourdon tube pressure gauge with switch contacts
Wherever the process pressure has to be indicated locally and, at the same time, circuits need to be switched, this switchGAUGE finds its use. Switch contacts consisting of several contacts can also be set to a single set point. Contact actuation is made when the actual value pointer travels beyond or below the desired set point. Inductive contacts can be used in hazardous areas. For triggering programmable logic controllers (PLC), electronic contacts and reed switches can be used. Features: • Also available with case filling for high dynamic pressure loads or vibrations • Instruments with inductive contacts for use in hazardous areas • Instruments with contacts for PLC applications • Safety version with solid baffle wall (Solidfront) available • QR code on dial links to instrument-specific information
WIKA PGS21.100, PGS21.160 Bourdon tube pressure gauge with switch contacts
Wherever the process pressure has to be indicated locally and, at the same time, circuits need to be switched, the model PGS21.1x0 switchGAUGE finds its use. Switch contacts (electrical alarm contacts) make or break an electric control circuit dependent upon the position of the instrument pointer. Switch contacts consisting of several contacts can also be set to a single set point. Contact actuation is made when the actual value pointer travels beyond or below the desired set point. As switch contacts, magnetic snap-action contacts, reed switches and electronic contacts are available. For triggering programmable logic controllers (PLC), electronic contacts and reed switches can be used. Features: • High reliability and long service life • Up to 3 switch contacts per instrument • Instruments with electronic contacts for PLC applications • Contact gauges comply with DIN 16085
WIKA PGS23.063 Bourdon tube pressure gauge with switch contacts
Wherever the process pressure has to be indicated locally and, at the same time, circuits need to be switched, this switchGAUGE finds its use. Switch contacts consisting of 2 contacts can also be set to a single set point. Contact actuation is made when the actual value pointer travels beyond or below the desired set point. Features: • Up to 2 switch contacts per instrument • Instruments with inductive contacts for use in hazardous areas • Instruments with contacts for PLC applications • Safety version with solid baffle wall (Solidfront)
WIKA PGS21 Bourdon tube pressure gauge with switch contacts
The model PGS21 switchGAUGE offers the usual analogue indication, which can be read on-site irrespective of the power supply, and in addition the possibility to switch a potential-free electrical signal. Depending on the pointer position, the circuit will be opened or closed. Thus the switchGAUGE can be used actively for process monitoring, for example to monitor the level of a gas cylinder or a hydraulic circuit. Features: • High switching reliability and long service life • With up to two magnetic snap-action contacts or one reed switch • Set points fixed to customer requirements • Increased ingress protection, IP65 • Scale ranges from 0 ... 2.5 to 0 ... 400 bar [0 ... 60 to 0 ... 6,000 psi]
WIKA PGS43.100, PGS43.160 Diaphragm pressure gauge with switch contacts
Wherever the process pressure has to be indicated locally, and, at the same time, circuits are to be made or broken, the model PGS43.1x0 switchGAUGE can be used. Switch contacts (electrical alarm contacts) make or break an electric control circuit dependent upon the position of the instrument pointer. Features: • High reliability and long service life • Wide choice of special materials • Up to 4 switch contacts per instrument • Also available with liquid filling for high dynamic pressure loads or vibrations • Instruments with inductive contacts for use in hazardous areas • Instruments with contacts for PLC applications
WIKA PGS25 Bourdon tube pressure gauge with electronic pressure switch
The model PGS25 switchGAUGE offers the usual analogue indication, which can be read on-site irrespective of the power supply. Additionally the instrument is capable of switching up to two transistor outputs. The stainless steel case fulfils the requirements of IP65 ingress protection. The resistance to shock and vibration can be increased by the silicone oil case filling. Thus the instrument is perfectly suited for use in harsh industrial environments. Features: • Non-contact sensor (wear-free) • Robust stainless steel case • Scale ranges 0 ... 1.6 to 0 ... 400 bar or 0 ... 30 to 0 .... 6,000 psi • NPN or PNP switching outputs • Both switch points factory-programmable between 5 ... 95 % of the scale range
WIKA DPGS43.100, DPGS43.160 Differential pressure gauge with switch contacts
Wherever the process pressure has to be indicated locally and, at the same time, circuits need to be switched, the model DPGS43.1x0 switchGAUGE finds its use. Switch contacts (electrical alarm contacts) make or break an electric control circuit dependent upon the pointer position of the pressure gauge. Features: • Differential pressure measuring ranges from 0 ... 16 mbar • High working pressure (static pressure) and high overload safety up to 40 bar • Also available with liquid-filled case for high dynamic pressure loads or vibrations • Instruments with inductive contacts for use in hazardous areas • Instruments with switch contact for PLC applications
