Connectors
PC TESY offers connectors for thermocouples and resistance thermometer connection to measuring circuit.
Thermocouple connectors correspond to standards ASTM E1684 and ASTM E1129. They have error not more than 1,1°С under connector temperature difference equal to 40°С. The error is reduced in proportion to connector temperature difference reduction.
Material of connectors resists temperature up to 200°С. Connector temperature during operation should not exceed temperature of compensation wires, that are used by the customer for thermocouple connection to measuring circuit.
Dust and water protection rate according to GOST 14254-96 (IEC 60529): IP40.
