M0305 series

Product catalog summary

Overview: This document provides technical specifications and guidelines for pressure gauges manufactured by Gesa Termómetros S.L., designed for challenging operating conditions such as vibrations and rapid pressure changes. These gauges are suitable for systems with low viscosity fluids that do not attack copper alloys, like cooling systems.

Specifications:

Materials: The case is made of AISI 304 stainless steel, while the Bourdon tube, moving parts, and threaded connection are made of AISI 316 stainless steel. The display is polycarbonate, and the dial and pointer are lacquered aluminum.
Design Standards: Manufactured according to EN 837-1 standards.
IP Protection: Rated IP65 as per EN 60529 / IEC 529.
Accuracy: Class 1.6.
Pressure Limits: Static pressure is ¾ of the end scale, maximum pressure is full scale for a short period, and oscillating pressure is ⅔ of the end scale.
Temperature Limits: Environment: -20 to +50°C; Fluid: up to 100°C.
Threaded Connections: Vary by gauge size: Ø63 uses ¼” BSP, Ø80 uses ⅜” BSP, and Ø100 uses ½” BSP.
Antivibration Fluid: Glycerine 99.8%.
Range: -1 to 1000 Bar.

Applications: These gauges are used in ship supplies, irrigation systems, air conditioning, the food industry, pneumatics, and hydraulics.

Ordering Information:

Case Diameter: Options include Ø63, Ø80, Ø100.
Pressure Range: Various options from -1 to 1000 Bar.
Threaded Connection: Multiple options including ¼” BSP, ½” BSP, and others.
Mounting: Options A, B, C, or D as per attached diagram.
Calibration Certificate: Available with or without a 7 Points Certificate traceable to ENAC.

Additional Features: The pressure gauge includes an overtemperature relief system with an upper plug and is available with different scale options (Bar/Psi, Bar, or cmHg).
