Smart Temperature Transmitters

  • Smart temperature transmitters used for various industrial applications. It can accept input from RTD, all types of thermocouples & temperature signal is transmitted in the form of electrical 4 – 20 mA signal. The on-line temperature indication is provided through LC D. Span / Zero adjustments are easily accessible.
  •   4-20 mA HART Compatible.
  •  Single-Sensor and Dual-Sensor Inputs.
  • Enclosure: Die Cast Aluminum/ SS.
  •   Enclosure Protection Class IP-67.
  • Enhanced display with Local Operator Interface.
  •  Differential & Redundant temperature measurement.

Thermocouple / Rtd

  •  A Thermocouple is a sensor used to measure temperature. Thermocouples consist of two wire legs made from different metals. The wires legs are welded together at one end, creating a junction. This junction is where the temperature is measured. When the junction experiences a change in temperature, a voltage is created.
  • There are many types of thermocouples, each with its own unique characteristics in terms of temperature range, durability, vibration resistance, chemical resistance, and application compatibility. Type J, K, T, & E are “Base Metal” thermocouples, the most common types of thermocouples. Type R, S, and B thermocouples are “Noble Metal” thermocouples, which are used in high temperature applications.
  • Limits of error for Type J, K & B are as per ANSI MC 96.1 and for S & R as per IS.
  • Elements with special limits of error, other diameters and ANSI types e.g. T,E & N also available.
  •  Calibration report for each thermocouple with traceability to NPL is optionally available to meet ISO 9000 requirements.
  •  Protecting Sheath is available in mild steal, stainless steel.
  • Protecting Sheath is available in mild steal, stainless steel 304,310,315,446,inconel600,incolly800,wrought iron, impervious ceramic, sintered-Alumina, silicon carbide.
  •   Response Time Is 6sec (63.2%) for 6mm OD sheath.


  • Thermowell are tubular fittings used to protect temperature sensors installed in industrial processes. A temperature sensor such as thermometer, thermocouple or Resistance Temperature Detector is inserted in the open end of the tube, Thermodynamically, the process fluid transfers heat to the thermowell wall, which in turn transfers heat to the sensor.
  • A thermowell is typically machined from solid bar stock and gun-drilled to ensure a long straight bore that closely approximates the diameter of the installed sensor. A thermowell is typically mounted into the process stream by way of a threaded, welded, sanitary cap or flanged process connection.
  • He temperature sensor such as a thermometer, thermocouple or resistance temperature detector is inserted in the open end of the thermowell and typically spring-loaded to ensure that the outside tip of the temperature sensor is in metal to metal contact with the inside tip of the thermowell.
