1 SPRING LOADED RESISTANCE THERMOMETER CONFIGURATIONS FOR USE WITH THERMOWELLS II 1G/D Ex ia Pt100RI/WI S10 S11 S16-1 S16-2 1

2 FEATURES TECHNICAL SPECIFICATION ASSEMBLY The industrial spring loaded configuration guarantees a positive contact between the sensing part of the temperature probe and the bottom of the thermowell, thus reducing the response time. In order to calculate the correct element length, we need the Z-length: this is the total bore depth of the thermowell. All assemblies offer a variety of protection heads to meet environmental and size requirements of most applications. High vibration resistant models available 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 Extension N : stainless steel SS316L Nipple-union-nipple. Minimum construction length 110 mm In order to achieve longer lengths, pipe nipples will be used.. ATEX : code A G=gas D=Dust IECEx : code I G=gas D=Dust 2

3 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, T amb =20 C Conductors: material Cu Metal sheath: SS321 / Terminal block: -ceramic: code PCC -hi-tech thermoplast: moisture and shockproof: codes PCA or PCB -mounting plate with flying leads: code PFA Accuracy: according IEC DIN EN 60751: see table below PCC PCB PCA PFA 3
