Brief Introduction

SH-JYDZ-L7

Rated voltage: 300V / 500VConductor material is tin-plated copper / nickel-chromium / copper, etcShielded copper wire braided / tinned copper braided / aluminum / polyester composite film, etcOperating temperature of normal grade: -40'C~105°CThe model of the compensation conductor is divided into SC, KC, KX, EX, JX, TX, NC according to the product variety, and the first letter of the model corresponds to the degree mark of the thermocoupleThe letter "X" means the extended compensation conductor (type)V-Polyvinyl chloride material (PVC)The letter "C" indicates the compensating compensation conductor (type)H-indicates compensation wire for heat resistanceS-represents the thermoelectric characteristic tolerance as a precision level compensation leadF-PTeflon materialR-indicates a multi-stock compensation conductorB-alkali-free glass-wire materialP-represents a compensation wire with a shield layerG-indicates a general compensation wire1. Selection of compensation wire The compensation wire must be correctly selected according to the type of thermocouple used and the occasion used, for example: K-type couple should choose the K-type couple compensation wire, according to the use occasion, select the working temperature range, usually KC working temperature is-20~100℃, the wide range is-25~200℃. The normal level error is + 2.5℃ and the precision level is + 1.5℃2, the connection and the thermocouple terminal 2 contact as close as possible, try to keep the temperature of the two contacts, and the instrument terminal connection as much as possible, the instrument cabinet has a fan, the contact should protect not make the fan blow directly to the contact.3. Length of useBecause the signal of the thermocouple is very low and is at the microvolt level, if the distance used is too long, the attenuation of the signal and the interference of strong electricity in the environment can distort the signal of the thermocouple, resulting in inaccurate measurement and control temperature, and serious temperature fluctuations will be generated in the control.
