PT30 - Ø6mm, cable lead
PT37 - Ø4 or 3mm, wire leads
PT38 - with the hole for a bolt Ø4,2 mm

PT34 - in teflon sleeve (low price)
PT33 - flat design (to be mounted in a motor groove)
PT36 - embedded, insulating jacket
 
PT35 - adjustable collet nut
PT31 - firmly welded nut
 

      All thermometer models featuring the lead-in wires firmly fastened to the thermometer body are termed cable thermometers. Metal parts are made of grade 17248 stainless steel. The lead wire length as well as the mechanical design may be customized.
Type: Description: Temperature range: Leads: Casing material:
PT30 Cable type, surface mounted contact design, Ø6mm (Ø5mm on request), to be fitted on the pipeline with a fastener band. Pt100/B sensor, four-wire connection. -40..+200°C
Special design: up to +350°C
4w cable 200°C 1m
2w cable 350°C 1m
stainless steel of 17248 grade
PT31 Design similar to that of PT30. Fixing bolts M12x1.5 are welded to the shank.M12x1.75, G1/2, M20x1.5 or other type bolts can also be used. Submerged length "Y" according to requirements. -40..+200°C
Special design: up to +350°C
4w cable 200°C 1m
2w cable 350°C 1m
stainless steel of 17248 grade
PT33 Flat design for mounting into a stator groove in electric rotating machines. The sensor is cemented into a glass-textile plate. It is protected from outside by means of a special shrinking sleeve. max. +180°C (class "H") 2 stranded wires, 200°C 2,5m glass textile+ teflon
PT34 This is a miniature, very fast-response thermometer, designed to be mounted into the windings of electric machines. The Pt100 sensor is protected by a special teflon shrinking sleeve. Max. +200°C 2 stranded wires, 200°C 2,5m teflon sleeve
PT35 Cable-mounted thermometer, Ø8mm, with collet nut M12x1.75 or G1/2, adjustable submerged length. It has been designed to measure, e.g., the bearing temperature in large rotating machines. The adjustable nut is not pressure-tight. -40..+120°C 4w cable 200°C 2,5m stainless steel of 17248 grade
PT36 Thermometer of approx. Ø3.5mm for insertion into electric machine winding. The sensor is embedded in an isolating sleeve - the casing is not exactly cylindrical. -40..+150°C (class "F") 2 stranded wires, 200°C 2,5m isolating sleeve
PT37 Ø4mm stem design, Ø3mm available on request. Max. +200°C
Special design: up to +400°C
2 stranded wires, 200°C 1m
2 silver wires
   (glass fibre insulation)
stainless steel of 17248 grade
PT38 To measure surface temperature. Design similar to that of PT30, the stem end is flat, with a Ø4.2mm hole for bolt fastening to the surface measured. For preliminary measurements only. -40..+200°C
Special design: up to +350°C
4w cable 200°C 1m
2w cable 350°C 1m
stainless steel of 17248 grade

- Insulation of the 4w 200°C cable (four 0.22 mm2 wires) (from inside outwards): teflon layer, wire braiding, silicon (by request also teflon)
- Insulation of the 2w 350°C cable (0.35mm2 wires): glass fibre plus metal wire braiding on each wire
- The 200°C stranded wire: it is a copper stranded wire, 0.35mm2, silver plated, with teflon insulation
