PLASTECH make Thermocouples are widely used in various industries as Temperature Sensing Elements. They are important element of dependable Temperature measurement.

PLASTECH make thermocouple assemblies for practically every application covering R & D requirements to furnace temperature. Our services are also available to design and fabricate special purpose thermocouple assemblies as per customer's design and specifications.

Types of thermocouples available are 'J' (Iron-Constantan),
T (Copper-Constantan), K (Chormel - Alumel), S (Pt/Pt-Rh 10%),
R (Pt/Pt-Rh 13%) & etc.


RESISTANCE TEMPERATURE DETECTORS (RTD) :-

PLASTECH make RTD employs high purity electrical resistance wire, non - inductively wound on ceramic or glass base material. When RTD element subjected to heat it changes its electrical resistance value corresponding to variation in temp. and thermal coefficient. The most commonly used resistance element is platinum known as PT-100 (100 ohms at 0oC). The RTD characteristics have a standard pattern for different resistance elements like Copper, Nickel, Platinum etc.


THERMOCOUPLE (T/C) :-

PLASTECH make thermocouple employs two dissimilar metals. When two dissimilar metals welded together at one end subjected to heat, it develops a small DC voltage (EMF) corresponding to temperature difference between hot junction (measuring) and cold junction (reference). The temperature EMF characteristics have standard pattern for different type of thermocouple element like
T, J, K, R, S, etc.


MINERAL INSULATED ELEMENT (MI) :-

PLASTECH make mineral insulated (MI) sensors are insulated with tightly compacted magnesium oxide powder enclosed in various metal sheaths. Hot junction is formed in inert gas atmosphere and tested for leakage with Nitrogen gas under pressure. The MI sensors can be given from few inches to several meters. Sheath can be bend, twisted and flattened to suit application. The junction can be Ground or Ungrounded.


THERMOCOUPLE & RTD's WITH TRANSMITTER :-

Temperature transmitter in head mounting isolated / non-isolated / intrinsically safe type for RTD and Thermocouple.
