Product catalog summary

Overview: The document provides technical instructions for the NTFM 100 E series of industrial frictionless governor-operated pressure and temperature switches, specifically designed for Marine Nationale (French navy) applications. These components comply with DCN specifications and are ISO 9001 V2000 certified.

Specifications: The switches are designed to detect pressure and temperature in various fluids used on submarines and surface ships. They operate within specific physical ranges: relative pressure from -1 to 400 bar, absolute pressure from 50 mbar to 50 bar, differential pressure from 50 mbar to 10 bar, and temperature from -50 to 120°C.

Operating Principle: The switches use a force-balancing system where pressure variations are transmitted to a sensor, activating an internal mechanism. Adjustments can be made using a screw to set the operating point, and a wheel to adjust deviation values.

Construction: The detectors consist of gold-plated switches and a pressure sensor or temperature-sensitive component. They are housed in a mazak casing with an aluminium cover, providing IP 66 protection.

Electrical Function: Available in unipolar and bipolar options, the detectors support various electrical wiring configurations, including CAPRI-type, FCI/JUPITER, and DELAUNAY-type cable glands.

Electrical Characteristics: The switches operate at 28 Vdc with a current range of 1 to 100 mA. They have a contact resistance of ≤ 120 mΩ and can withstand mechanical resistance up to 2 million cycles.

Mechanical Characteristics: The devices offer repeatability of ±1% MR and a mean time between failures of over 200,000 cycles.

Environmental Conditions: The switches are designed to withstand shocks up to 60 g and operate within a temperature range of -20 to +70°C.

Instructions for Use: Special separators and dampeners are recommended for certain fluids and conditions. The units should be mounted away from heat sources and vibrations.

Glossary of Terms: Definitions for terms such as range, measuring range, nominal usage range, and others are provided to clarify the technical specifications.

Metrological Specifications: Detailed tables outline the specifications for temperature, gauge, absolute, and differential pressure switches, including deadband adjustments and technology types.

Coding System: The document explains the coding system used to identify different models and configurations of the switches, including options for naval finishing and electrical functions.

• Range: Lower and upper values of the adjustment range controlled by the detector. Metrological specifications tables in our technical specifications sheet feature low values, i.e. low controlled variable index values. • Measuring range (MR): Algebraic difference between upper and lower operating values. • Nominal usage range (NUD): Maximum upper limit (constant) for measurement and influence values without having to adjust detector specifications. • Non deterioration range (NDTR): Maximum upper limit (constant) for measurement and influence values without having to adjust detector specifications...
