[9] Cấp chính xác: (according to EN 13190)
- Class 1;
- Class 0,6 (on request - option V36).
Note: accuracy indicated on the thermometer does not consider the interference of an eventually applied electric contact.
[10] Capillary
- AISI 316 stainless steel, plain; (identification KZ)
- dAISI 316 stainless steel with flexible AISI 304 stainless steel armour. (identification KY) note: distance reading thermometers can be identified with the picture number, adding the relating reference of the capillary (K identification), to its material and its armouring (Z or Y identification), followed by the number indicating the length in meters of the same capillary.
[11] Capillary length
- Standard: 1, 2, 3 and 4 meters;
- Special: on request;
- Maximum: 25 meters.
[12] Sensitive bulb (see pages ST05 and ST06)
- 12 mm standard cylindrical diameter;
- 8 mm standard cylindrical diameter.
[13] Thermowell (see at pages PZ01 and PZ02)
- Built-up from pipe - P2 and P4 type;
- Đrilled from solid bar stock - P3 and P5 type (dimensions and materials are decided by the customer).
[14] Thermal drift
- With reference to the ambient temperature of 20 °C and due to the length of the capillary, thermal drift affects the instrument accuracy as ± 0,15% per meter every 10 °C of variations.
