DIN 43762 1986-03 PDF

Full title and description

STB DIN 43762 1986-03 — Measurement and control; electrical temperature sensors; sensor units (measurement inserts) for resistance thermometers. This document specifies the characteristics and dimensional/mechanical requirements for replaceable sensor inserts used in resistance thermometer assemblies.

Abstract

DIN 43762:1986-03 defines the form, mounting and basic requirements for measurement inserts (sensor units) intended for use in resistance thermometers (RTD inserts). It updates the earlier 1964 edition and is a short (4-page) technical specification used to ensure interchangeability and proper installation of RTD inserts in protection fittings and heads.

Scope

This standard covers sensor units (measurement inserts) intended for resistance thermometers: their intended function, general dimensions and fit for use in exchangeable measuring inserts and protection fittings. It applies to inserts that are installed in industrial protection fittings, heads and assemblies for temperature monitoring in ducts, pipes and plant equipment, and is intended to promote mechanical and electrical interchangeability.

Key topics and requirements

• Definition and classification of measurement inserts for resistance thermometers (RTD inserts).
• Dimensional and mounting features to ensure interchangeability with protection fittings and connection heads.
• Basic electrical connection types and terminal arrangements for sensor inserts used in RTD assemblies.
• Materials and constructional notes to support reliable measurement performance and reasonable response behaviour when installed.
• Reference to related DIN/IEC requirements for sensing elements (for example IEC/EN RTD element standards) and later DIN documents that update or replace aspects of this standard.

Typical use and users

Manufacturers of resistance thermometers and RTD measurement inserts, instrument designers, plant engineers and procurement specialists use this standard to specify and select replaceable sensor inserts that must mate with thermowells, protection fittings and terminal heads. Typical industries include process engineering, chemical plants, power generation and HVAC where standardized replaceable inserts ease maintenance and spare-part interchange.

Related standards

Standards commonly associated with DIN 43762 include other DIN publications covering protection tubes, thermowells and connection heads (for example DIN 43763, DIN 43764, DIN 43772) and international element specifications such as IEC/EN standards for resistance thermometer elements (IEC 751 / EN 60751). Users are typically advised to check newer DIN documents (for example DIN 43735 and related revisions) for current, consolidated requirements.

FAQ

Q: What is this standard?

A: DIN 43762:1986-03 is a short DIN technical specification that defines measurement inserts (sensor units) for resistance thermometers — i.e., the replaceable RTD elements and their mechanical/electrical provisions for mounting and connection.

Q: What does it cover?

A: It covers form, fit and basic requirements for RTD measurement inserts so they can be used interchangeably in protection fittings and connection heads; it does not replace detailed element performance standards (IEC/EN RTD element standards remain applicable for sensing-element tolerances and calibration).

Q: Who typically uses it?

A: RTD/thermometer manufacturers, instrumentation engineers, plant maintenance and procurement staff who need standardized, replaceable sensor inserts or who specify instrument mounting and terminal arrangements.

Q: Is it current or superseded?

A: This edition (1986-03) is listed as withdrawn/superseded in standards catalogues; DIN and standards sellers note later related DIN documents and suggest consulting newer DIN publications (and relevant EN/IEC standards) for current requirements. Check the issuing body for the most recent applicable documents before specifying.

Q: Is it part of a series?

A: Yes — DIN 43762 belongs to a family of DIN standards on electrical temperature sensors and protection fittings (DIN 43760–43772 series and related parts) that together address elements, inserts, protection tubes, heads and thermowells. Users typically reference several parts of the series when specifying complete RTD assemblies.

Q: What are the key keywords?

A: Resistance thermometer insert, RTD insert, measurement insert, DIN 43762, temperature sensor, interchangeability, protection tube, thermowell, connection head.
