Hazardous area equipment
Thermocouples, RTD sensors, transmitters and cable for Ex d, Ex e, Ex tD and Ex ia installations, gathered here from across our product types.
Check the certificate and drawing for the assembly you need. Tell us your area classification so we can confirm suitability before you order.
By protection type
Each link opens the product family, with its own drawings.
Ex d, Ex e and Ex tD sensors
Thermocouple and RTD assemblies. Drawings include SD 558, SD 572, SD 575 and SD 576.
Ex ia sensors
Thermocouple and RTD sensors for intrinsically safe circuits. Drawings carry an Ex ia suffix, such as SD 050 Ex ia and SD 145 Ex ia.
Ex ia transmitters
Head mounted 2 wire HART transmitter, part number TCTXEXI
Hazardous area cable SWA
Steel wire armoured thermocouple and RTD cable, listed with Cables
Sensors in intrinsically safe circuits
Thermocouples with insulated junctions and RTD sensors supplied for Ex ia circuits are subjected to the tests listed here, and a certificate of test is supplied. The sensor carries a label.
Sensors must meet the dielectric strength requirement of AS/NZS 60079.11. Ask us which sensors in the price list can be supplied this way.
Tests carried out
- Visual and dimensional inspection
- Insulation resistance, minimum 1000 MΩ
- Upscale polarity test
- Electrical continuity test
