TRANSMITTERS & SWITCHES - SINGAPORE

CONTACT BAYPORE-SINGAPORE

All pressure switches, differential pressure switches, vacuum switches, temperature switches, level switches and flow switches etc. are available in industrial/weatherproof form and for hazardous area installations in ATEX certified versions either as Flameproof (Explosion Proof) Exd or Intrinsically Safe Exia. IECEx certification is available on our Hermes, Perseus and Titan ranges in both Exd and Exia.

The industries serviced include but are not limited to, oil and gas production (onshore and offshore facilities), power stations (nuclear,coal,oil and gas), nuclear waste handling facilities, water companies, manufacturing/production, HVAC/refrigeration, defence organisations, shipping and railways.

PRESSURE SWITCH 

Pressure switches for hydraulics, pressure switches for water, pressure switches for air, pressure switches for gases, pressure switches for chemicals, pressure switches for fuel oil, pressure switches for sludge/mud/sewage, pressure switches for refrigerants (R134a and R407c), whatever the medium we have a pressure switch to suit.

All pressure switch ranges have demonstrated their reliability for application at SIL 2 IEC 61508, with a qualifying report and Certificate Of Compliance available on request

Pressure switches - Flameproof (explosion proof) either ATEX or dual ATEX/IECEx Exd certified for use in Category 2 (Zone 1) hazardous areas.
