  • NIPPON INSTRUMENTS (I) Pvt. Ltd. & NIPPON TECHNOLOGIES is in the field of manufacturing entire range of Temperature Sensors, Thermowells, Thermocouple Grade Extension, & Compensating Cables, RTD signal cables & accessories since 1989.
  • The sales of more than 2,50,000 sensors throughout India and globally is a testimony of quality products and services.
  • The custom-built sensors is what we like the most and we can cater to any of your applicational requirements.
  • Our manufacturing bases are well equipped with necessary testing facilities like Calibrators, mV source, RTD source, precision multimeters, insulation / HV testers, constant temperature, oil bath, high temperature furnace, gauges, dimension measuring, instruments etc... They are traceable to N.P.L., Delhi and tested at E.R.T.L./I.D.E.M.I.
Features:
 
  • Sensors in any type, size, shape and M.O.C. Each Sensor is tested and calibrated with E.R.T.L. / I.D.E.M.I. certified calibrators.
  • Very high accuracies and very small time constants due to improved manufacturing process like Argon Welding, Brazing and high quality components.
  • Special Sensors like Duplex, Glass Embedded, skin type, multipoint assembles, Pt46, group LLC etc... can be supplied.
  • Entire Digital Instrumentation range manufactured by us support these Sensors.
  • Thermowells to suit any size and shape of sensors.
  • EX-STOCK DELIVERIES OF STANDARD PRODUCTS.
  • SHORT DELIVERIES FOR CUSTOM BUILT SENSORS & THERMOWELLS.
  • Sold more than 2,50,000 sensors till date.

 

TIPS FOR SELECTION:

 
1. Thermocouples are preferred due to:
 
  • Faster response.
  • Wide Temperature Range.
  • Lower Costs.
  • Flexibility in designing.
  • Higher Mechanical strengths.
2. RTD's are preferred due to:
 
  • Better accuracies.
  • Better stability.
  • Repeatability.
3. Smaller Sheath Diamaters will give faster response. We can offer sheath dia. as low as 1.5mm.
 
4. Ungrounded Junctioned Sensors, through electrically isolated have sluggish response time. Electrical isolation better than 700 M at 500 VDC.
 
5. RTD's with 3 wire configuration compensates lead length resistance effect on temperature measurements as compared to 2 wire configuration.
