Gas in metal-expansion thermometers with alarm contacts

Product catalog summary
Overview: This document provides comprehensive instructions for the operation, installation, and maintenance of gas expansion thermometers (Type F) and alarm contacts with sliding and magnetic snap-action contacts (Type S/M) by Manfred Jünemann Mess- und Regeltechnik GmbH. It covers specifications, safety instructions, and technical data.
Specifications: The thermometers adhere to EN 13190, DIN 43772, and DIN 16179 standards. Selection should consider the medium's impact on materials, scale range, and version. Optimal performance is achieved when the operating temperature is within the middle third of the scale range.
Installation Guidelines: Installation should follow VDE/VDI directives 3511 and 3512. Use sealing washers per DIN 7603A with a torque limit of 80 Nm. Avoid tightening by the case; use wrench flats. Capillaries should not be axially distorted, and the mounting radius should be at least 30 mm.
Safety Instructions: Electrical connections must be made by qualified personnel, following national safety regulations (VDE 0100). Overcurrent protection is not included and should be installed according to EN 60947-5-1 if necessary.
Maintenance: Devices are maintenance-free but should have their indication and switching functions checked annually. Repairs should be performed by the manufacturer.
Technical Data: The document includes tables with maximum contact load specifications for resistive and inductive loads, detailing sliding and magnetic snap-action contacts. Contact material is silver-nickel, with a maximum operating voltage of 250 V.
Storage: Devices should be stored in original packaging at temperatures between -40°C and +70°C to prevent damage.
General Overview: Instructions for electronic limit switches used with PLC units or other devices are provided. These switches operate with auxiliary voltage from 10 to 30 V DC and offer immediate signaling based on pointer movement.
Mounting Instructions: Follow general technical regulations for pressure and temperature measuring devices (EN 837-2 or EN 13190). Avoid locations with excessive vibrations to ensure proper function and longevity.
Electrical Connection: Connections should be made by qualified personnel. Terminal locations and switch functions are indicated on the device's rating plate. Proper marking of the earth terminal and connectors is essential.
Safety Precautions: National safety regulations must be observed during installation, commissioning, and operation. Work should be conducted with the power source disconnected, and only skilled personnel should handle these instruments.
Set Pointer Adjustment: The set pointer can be adjusted using the supplied adjusting key, adjustable across the entire scale range.
Maintenance: Devices are maintenance-free, but indication and switching functions should be checked once or twice a year. This involves separating the gauge from the process and applying a pressure or temperature standard. Repairs should only be conducted by the manufacturer.
Technical Specifications: Includes specifications for different contact types (type-S and type-M) and their voltage, current, and power ratings, along with contact materials and maximum contact load with resistive load.
Additional Notes: For mounting measuring gauges onto pressure or temperature tapping points, refer to specific instruction manuals for each model with their respective article numbers.
