Riedon - High Precision Resistors

Custom RTD elements, Power resistors as heating elements. Compensation Resistors, Metal and Thick Film networks and arrays.

Riedon - High Precision Resistors

These Precision Shunt Resistors are designed for systems which have a fast changing electrical load. It has a Heatsink and is encapsulated in epoxy. The substrate is Alumina for Good Heat Transfer but with Electrical Insulation. It is a Resistor formed by a NiCr Foil. (Like Nichrome).

Precision Resistors - UNS 4-T220 - Riedon

Specifications
  • Resistance from 0.2 Ohm to 80 Ohms
  • Power Rating to 15 Watts
  • Resistance Tolerances to ±0.01%
  • TCR to ±1ppm/K
  • Load Stability to 0.01%
Resistors are probably the most common and well known of all electrical components. Applying a resistor to a circuit normally requires (1) calculating the nominal values needed in the circuit application (resistance, power rating, etc.) then (2) developing acceptable tolerances for the resistor that ensure it will function properly in all extremes of the application.

Read up the "Temperature dependence and TC" - The absolute ohmic value of a resistor is temperature-dependent. Also the "Definition of terms in the specifications of Resistors."

Elcometer 215 Oven Data Logger

The logger measures temperatures and stores them for a specified amount of time. The instrument measures continuously but takes and saves readings at time intervals set by the user. The maximum recording period depends on the number of sensors being used and the specified recording interval.
