DIRECT IMMERSION RESISTANCE THERMOMETER CONFIGURATIONS WELDED THREADED CONNECTION II 1G/D Ex ia Pt100KI D20 D21 D26-1 D26-2 1
FEATURES The industrial thermometer configuration guarantees a short response time. The sensor is directly immersed into the medium. Fully welded construction. All assemblies offer a variety of protection heads to meet environmental and size requirements of most applications. High vibration resistant models available. TECHNICAL SPECIFICATION ASSEMBLY Connection head Aluminium With external earth terminal Ambient temperature range: -40/+100 C IP 6X protection degree (body cover) with oil-proof rubber O-ring, when used with correct cable gland Epoxy finish; colour blue RAL5015 Cover: hinged type or screw type with chain Sensor material: SS321 / 1.4541 Other on request ATEX : code A G=gas D=Dust IECEx : code I G=gas D=Dust Technical specification sensor insert High quality PT100 element with MgO mineral insulated metal sheathed cable, providing excellent stability and reproducibility. The unique properties make this basic element ideally suited for a wide range of applications up to 550 C. The PT100 is bendable over the total length except on the tip over 50 mm. Maximum temperature: 550 C Minimum insulation resistance: 1000 MOhm at 500VDC, ambient Conductors: material Cu Metal sheath: SS321 / 1.4541 Terminal block: -ceramic -hi-tech thermoplast: moisture and shockproof -mounting plate with flying leads Accuracy: according IEC DIN EN 60751: see table below 2
