Differential pressure switch
規格介紹:WIKA DPS40
Differential pressure switch
詳細介紹:
The differential pressure gauges of the DELTA-line product family are primarily used for the monitoring and control of low differential pressures where there are high requirements in terms of one-sided overload and static pressure.
Typical markets for these products are the process heating technology, the heating, ventilation and air-conditioning industries, the water/wastewater industry, and machine building and plant construction. For these, the main function of the measuring instruments is the monitoring and control of filters, compressors and pumps.
Features:
- • With one or two adjustable micro switches
- • Shatterproof window and robust aluminium or stainless steel measuring chamber for increased
- requirements
- • Optionally with approvals for hazardous areas
- • High ingress protection, IP65, for outdoor use and processes with high condensation
- • Low measuring range from 0 ... 250 mbar

WIKA 736.51+8xx Differential pressure gauge with switch contacts
The model 736.51 capsule pressure gauge is based upon the proven capsule measuring system and is suitable for very low pressures. On pressurisation, the expansion of the capsule element, proportional to the incident pressure, is transmitted to the movement and indicated. Features: • Differential pressure measuring ranges from 0 … 2.5 mbar • Ingress protection IP66 • Case and wetted parts from stainless steel • Version with switch contact for PLC applications
WIKA 700.01, 700.02 Differential pressure gauge
Model 700.01 is particularly intended for the monitoring of differential pressures even in the case of high working pressures in gas and air preparation and supply systems. Model 700.02, the version with a separation diaphragm, is suitable for liquid media and therefore also for water treatment and supply systems. Features: • Differential pressure measuring ranges • Model 700.01: from 0 ... 400 mbar to 0 ... 10 bar • Model 700.02: from 0 ... 160 mbar to 0 ... 2.5 bar • Compact system case from stainless steel, suitable for high working pressures (static pressures) selectable, 100, 250 or 400 bar (model 700.02 up to a max. 100 bar) • Overpressure safe either side to maximum working pressure • System and/or case of indication may be changed locally • Up to 2 reed contacts may also be adjusted and retrofitted locally
WIKA 712.15.100, 732.15.100 Differential pressure gauge
These high-quality gauges are characterised by their compact and robust design and are primarily used for level measurement on liquid gas tanks. With 11 different measuring cells all usual tank sizes in cryotechnology are covered. As a result of the large measuring range overlap of the respective measuring cells, the gauge installed on the tank can be adjusted to match a whole variety of gases such as Ar, O2, N2 or CO2, with a full-scale deflection over a complete 270 degree sweep. Features: • Differential pressure measuring ranges from 0 … 80 mbar to 0 ... 1725 mbar • High working pressure (static pressure) of 50 bar • Overpressure safety either side up to 50 bar • Very compact design • Optionally compact valve manifold with working pressure indication
WIKA 712.15.160, 732.15.160 Differential pressure gauge
These high-quality differential pressure gauges are notable for their compact and robust design and are primarily used for level measurement on liquid gas tanks. With 6 different measuring cells, all usual tank sizes in cryotechnology are covered. The large overlap in measuring ranges of the measuring cells enables the setting for gas types such as Ar, O2, N2 or CO2 over the entire scale with 270 angular degrees. Features: • Differential pressure measuring ranges from 0 … 40 mbar to 0 ... 4,000 mbar • High working pressure (static pressure) of 50 bar • Overpressure safety either side up to 50 bar • Scalable measuring ranges (maximum turndown of 1 : 3.5) • Compact valve manifold with working pressure indication (optional)
WIKA A2G-90 Differential pressure gauge with pressure switch
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
