Pressure gauge with plastic case

Product catalog summary

Overview: This document outlines the technical specifications and ordering details for pressure gauges by Gesa Termómetros S.L., suitable for various applications such as compressed air, compressors, air conditioning, hydraulics, pneumatics, ship supplies, irrigation systems, food industry, and gas facilities.

Specifications:

Design Standards: Gauges comply with EN 837-1 or EN 837-3 standards.
Materials: Cases are made from polyethylene, carbon steel, AISI 304 stainless steel, and zincked carbon steel. Sensor elements include Bourdon tubes and capsules made from copper alloy or AISI 316 stainless steel.
Pressure Limits: Static pressure is up to ¾ of the scale, maximum pressure is full scale for short periods, and oscillating pressure is up to ⅔ or 0.9 of the scale depending on the model.
Temperature Limits: Environmental temperature ranges from -40°C to 80°C, with fluid temperatures up to 100°C or 200°C depending on the connection material.
IP Protection: Ranges from IP43 to IP65 based on the model.
Accuracy: Varies by model and size, with classes ranging from 1.0 to 2.5.

Applications: Suitable for monitoring pressure in systems not subjected to vibrations and compatible with gaseous and liquid media that do not obstruct the pressure system or attack copper alloy parts.

Ordering Information: Customers can specify case diameter, pressure range, pressure scale, mounting type, threaded connection, connection material, and calibration certificate requirements. Options for antivibration fluid and overtemperature relief systems are available.

Dimensions and Weight: Detailed dimensions and weights are provided for each model, varying based on case diameter and mounting type.

Pressure Gauge System Recommendations: It is advised to separate the pressure gauge system from the liquid to prevent damage. Heat sinks are recommended to protect gauges from high temperatures. Common accessories include coil dampers, cooling towers, valves, and capillaries.

Vibration and Pulsation Management: For systems with severe vibrations, filling the manometer with glycerine or silicon oil can prevent pointer vibration. Pressure limiters and dampers are recommended for systems with significant pressure changes.

Pressure Limiter Specifications: Protect instruments from exceeding pressure limits, adjustable to block ducts when maximum pressure is exceeded. Standard parameters include a maximum pressure of 600 Bar.

Cooling Tower Specifications: Protect gauges from high process temperatures, supporting a maximum pressure of 1000 Bar, made from AISI 316 stainless steel.

Accessories and Materials: Accessories like coil dampers, capillary extensions, and pointer dampeners are available to protect gauges from high temperatures and pressure fluctuations.

Ball Valve Specifications: Constructed according to European standards, used for opening and closing applications, not recommended for partially open services under high pressure drops.

Calibration Process: Involves comparing the instrument's output with a standard to ensure accuracy. Calibration certificates include detailed information about the instrument, calibration method, and results, with a typical issuance deadline of 5 days.
