rtd cables manufactured by revti electronics industries are used as connecting lead wire between rtd sensor and temperature indicator device. Rtd cables are made in 2 core, 3 core, 4 core and 6 core configurations. 3 cores being the most commonly used configuration.
construction :-
rtd cables are made in three common constructions for making them suitable for different situations. These are ptfe/ptfe insulated. This is the most common construction. In this the cores are insulated with ptfe and then cores are twisted and jacketed with ptfe/ptfe/fg. In this construction cores are of ptfe and jacket is of fiber glass braid. This is used when rtd cable has to be installed in high temperature environment.
ptfe/spc/ptfe :-
in this construction, a spc wire braid shield is provided between twisted cores and jacket. This type of cable is used where higher accuracy is required. The current and voltage signals in rtd cables are of very small magnitude and can get affected by external electromagnetic noises produced by external devices such as motors, electronic equipments etc. Near the cable. The spc shield is grounded from one end and this protects the signals in the cable from these external noises.
construction :-
rtd cables are made in five common constructions
1. Ptfe /ptfe2. Ptfe/ptfe/fg3. Ptfe/ptfe/ss4. Ptfe/ptfe/spc5. Ptfe/ptfe/fg/ss
Relying on our experience in the industry gained over years, we, as a Manufacturer, Exporter & Supplier of RTD Cables have positioned us in the top string of the industry. They are applied as connecting lead wire between RTD sensor and temperature indicator device. The available configurations are 2 core, 3 core, 4 core and 6 core. The most common configuration is 3 cores.
ConstructionRTD Cables are made in three common constructions for making them suitable for different situations. These are PTFE/PTFE insulated. This is the most common construction. In this the cores are insulated with PTFE and then cores are twisted and jacketed with PTFE/PTFE/FG. In this construction cores are of PTFE and jacket is of Fiber glass braid. This is used when RTD cable has to be installed in high temperature environment.
PTFE/SPC/PTFEIn this construction, a SPC wire braid shield is provided between twisted cores and jacket. This type of Cable is used where higher accuracy is required. The current and voltage signals in RTD Cables are of very small magnitude and can get affected by external electromagnetic noises produced by external devices such as motors, electronic equipments etc. near the cable. The SPC Shield is grounded from one end and this protects the signals in the cable from these external noises.
Construction
Thermocouple wires & cables are used to make or extend signals from a thermocouple. Thermocouple wire is used in a thermocouple from the sensing point to the cold junction compensation point (or reference point).
It is the difference in the millivolt output from the sensing point to the reference point that provides the temperature measurement. Different thermocouple types require different alloy wire combinations.
Some of the more popular thermocouple wire & cable types includeType E (Chromel/Constantan), Type J (Iron/Constantan), Type K (Chromel/Alumel), andType T (Copper/Constantan)

Determined to present the utmost quality, we are involved in offering Thermocouple Cables. They are applied for making or extending signals from a thermocouple. They are also applied in a thermocouple from the sensing point to the cold junction compensation point (or reference point). It provides the temperature measurement as it is the difference in the millivolt output from the sensing point to the reference point. Different alloy wire combinations are applicable in different thermocouple types.
