Thermoelectric converters combined PTC 01 AU

PTC 01 are designed to convert AC coolant temperature pressurized water reactors and reactors of other types, as well as air temperature, and gaseous non - corrosive environments turbine casings into a proportional electrical signal (t. e. r. s. or resistance), including compensation t . e. r. s. "Cool Links" thermoelectric converters PTK - 01 speakers.

PTC - 01 speakers are designed for use in the measurement of information systems and automated process control system of nuclear power plants, as well as in other industries.
PTC - 01 AC comply with safety class according to NP 2H 306.2.141.
PTC - 01 AC meet seismic category of I according to PNAE G - 5 - 006.
Operating temperature transformation range PTC 01 AC - from minus 50 to 400 ° C (for certain embodiments of PTC 01 with the AC resistance transducers - from minus 50 to 200 ° C).
Nominal operating temperature range - from 250 ° C to 350 ° C.
PTC 01 AU with thermoelectric transducers (PT) produced 1st or 2nd class accuracy.

 

Upon request, the PTC 01 AU with PT NSH «K» and «N» can be made with individual calibration.

PTC produced 01 AC devices without built - in compensation t. e. r. s "cold junctions".
According to State Standard 2858 PTC 01 with AC resistance transducers (PMT) NSH with Pt50, Pt100, Pt500, Pt1000 produced with the tolerance class A, B, C (W100 = 1,385055).
Thermal inertia PTC 01 AU depending on performance of not more than:
- 0.3 - TP with bare;
- 1.0 to - with isolated FET;
- 3.0 s - with built - in calibration TSP;
TSP for PTK - 01 AC:
- 5.0 to - submersible diameter portion (4 - 5) mm;
- 20.0 s - submersible diameter portion (6 - 8) mm;
- 40.0 s - Immersion diameter (9 - 10) mm.
The tightness to the medium of the PTC 01 AC - tight.
In terms of resistance to mechanical stress PTC 01 AC - vibration and vibration - proof, shock - proof and earthquake - proof.
On protection from exposure to the environment of the PTC 01 speakers are protected against the ingress of dust and water, degree of protection - IP - 65.
If there is contact with the metal part Fr protective PTC fittings 01 AC - insulated and uninsulated.
Fr made of thermocouple cable according to GOST 3885 with mineral insulated thermoelectrodes which form thermoelectric couples K or N. cable diameter - 1.5; 2.0; 3.0; 4.5; 6.0; 8.0 mm depending on the performance of the PTC 01 AU.
PTC 01 AU can be made of a thermocouple cable sheath of heat resistant alloy to a temperature of 1000 ° C (analogous to Inconel 600) and 1260 ° C (or similar Pyrosil Super HT).
PTC - 01 speakers include:
- mode of application - to products with a continuous application mode;
- to repair and restore capabilities - to non - repairable and non - renewable products;
- the number of levels of functioning - to articles having three types of operation: the nominal level, partial failure and rejection;
- the number of functions - a dual - function products;
- the number of channels to single - channel, dual - channel and triple - channel products.
