Product catalog summary

Overview: The document provides comprehensive specifications and options for Resistance Temperature Detectors (RTDs) by Delta-Weed, detailing various models, configurations, and technical parameters.

Specifications:

Temperature Coefficient of Resistance (TCR): Determined by the purity of the winding wire, with specific values for Platinum, Nickel, and Copper.
Long-Term Stability: Sensors maintain accuracy over a year with minimal resistance change.
Repeatability: Sensors consistently reproduce the same output at a given temperature within specified limits.
Self Heating: Describes the temperature rise due to power dissipation, with specific data for different sheath diameters.
Response Time: Time required for sensors to reach a certain percentage of temperature change, varying by sheath diameter.
Temperature Range: Different codes specify minimum and maximum operating temperatures, with corresponding sheath materials.
Maximum Sheath Pressure: Pressure ratings for different sheath materials and diameters at various temperatures.
Insulation Resistance: Minimum resistance between lead wire and sensor sheath at a specified voltage.
Vibration Capability: Sensors can withstand specific vibration levels for a limited time.
Accuracy: Defined by DIN Class B and Class A standards, with specific tolerances at various temperatures.

Models and Options:

Model 110 and 310: Cuttable RTD sensors with options for spring-loaded nipples and various wire configurations.
Model R Series: General-purpose RTDs with options for tip sensitivity and fast response.
Model RH: General-purpose RTDs with weatherproof housing and various electrical entry options.
Model RP: RTDs with pockets, offering different connection heads and process connections.
Model RN/RU: Spring-loaded RTDs for use with thermowells, featuring various connection heads and transmitters.
