規格介紹:WIKA MA
Diaphragm pressure switch, flameproof enclosure Ex d
詳細介紹:
In production, the switches are traced by quality assurance software at every step and subsequently are 100 % tested. The robust switch enclosure from aluminium alloy can withstand the rough and corrosive operating conditions of the process industry with working ranges of up to 600 bar.
The pressure switch is fitted with 1 or 2 microswitches, which make it possible to switch an electrical load of up to AC 250 V, 20 A directly.

WIKA PCS Compact pressure switch
Due to its compactness, the model PCS pressure switch can be installed in measurement environments with limited space. The robust switch enclosure from aluminium alloy or stainless steel 316L can withstand the rough and corrosive operating conditions of the process industry with working ranges of up to 1,000 bar.
WIKA BA, BAX Bourdon tube pressure switch
In order to ensure as flexible operation as possible, the pressure switches are fitted with micro switches, which enable the switching of an electrical load of up to AC 250 V, 20 A directly. For lower switching power ratings, such as for PLC applications, argon gas-filled micro switches with gold-plated contacts can be selected.
WIKA A2G-42 Differential pressure switch
The model A2G-42 differential pressure switch is used for monitoring the differential pressure, overpressure and vacuum of air and other non-flammable and non-aggressive gases. Possible application areas are the control of air flows and the monitoring of filter contamination in HVAC/R systems as well as the monitoring of industrial air circuits. The setting of the switch point is made via an internal precision scale.
WIKA A2G-40 Differential pressure switch
The model A2G-40 differential pressure switch, in the Δp function, monitors filters and ventilators in ventilation ducts and air shutters. Six pressure range increments are available. The differential pressure switch is characterised by its simple mounting and high reliability.
WIKA DW, DW10 Differential pressure switch
In order to ensure as flexible operation as possible, the differential pressure switches are fitted with micro switches, which enable the switching of an electrical load of up to AC 250 V, 20 A directly. For lower switching power ratings, such as for PLC applications, argon gas-filled micro switches with gold-plated contacts can be selected.
WIKA DW03UN Differential pressure switch
In order to ensure as flexible operation as possible, the differential pressure switches are fitted with micro switches, which enable the switching of an electrical load of up to AC 250 V, 10 A directly. By using a diaphragm measuring system, the model DW03UN differential pressure switch is extremely robust and guarantees optimal operating characteristics and the highest measuring performances, with repeatability lower than 1 % of span. The process connection with a centre distance of 54 mm lower mount allows an easy and comfortable mounting of a standard valve manifold.
WIKA BWX Bourdon tube pressure switch
In order to ensure as flexible operation as possible, the pressure switches are fitted with microswitches, which enable the switching of an electrical load of up to AC 250 V, 20 A directly. For lower switching power ratings, such as for PLC applications, argon gas-filled microswitches with gold-plated contacts can be selected.
WIKA DC, DCC Compact differential pressure switch
In order to ensure as flexible operation as possible, the differential pressure switches are fitted with micro switches, which enable the switching of an electrical load of up to AC 250 V, 15 A directly. For lower switching power ratings, such as for PLC applications, argon gas-filled micro switches with gold-plated contacts can be selected.
