The ASTURO 400 bar pressure gauge with glass, item 013000I, is an analogue instrument designed for pressure control in pumps, coating systems, airless systems, product lines and high-pressure technical circuits. Its function is to allow the operator to read the system pressure immediately, check correct system operation, monitor variations and adjust settings when required. It is an essential accessory when pressure stability affects safety, supply continuity and application quality.

The image shows an analogue dial with dual bar and psi scale, with a measuring range up to 400 bar and approximately 6000 psi. This dual indication allows practical reading in environments where different pressure units are used. The front glass protects the dial and pointer, keeping the scale readable during use in workshops, coating departments or maintenance areas. The CE marking and EN 837-1 reference indicate that the product is intended for technical use in standard pressure monitoring applications.

The pressure gauge is designed for installation on compatible pumps and lines through a lower threaded connection. Before installation, thread compatibility, system pressure range, fluid or product type and installation position should be checked. A correctly selected pressure gauge allows working pressure to be monitored without operating too close to the instrument’s maximum range, improving readability, service life and operating safety. In high-pressure systems, monitoring the actual value is essential to avoid overloads, pressure drops, flow instability or unsuitable spraying conditions.

The accuracy class shown on the dial, KL 1.6, is an important element for assessing reading reliability. In this product, precision is not related to dimensional measurements, heights, transmission play or geometric errors, but to the ability to provide a consistent pressure reading in the circuit. Visual resolution depends on the dial scale and on the operator’s ability to correctly read the pointer position. For process checks, maintenance and system adjustment, a stable reading helps determine whether the pump is working under the expected conditions.

In a coating system, pressure is a key parameter. Pressure that is too low can cause irregular spraying, poor atomisation, insufficient coverage or unstable supply. Excessive pressure can increase material consumption, overspray, component stress and the risk of application defects. The pressure gauge therefore allows the system’s behaviour to be checked during operation and enables adjustments to the pump or line when the value is not consistent with the product used and the desired result.

The product can be used in body shops, workshops, finishing departments, industrial maintenance, airless systems and systems for paints, primers, enamels, protective products and compatible technical materials. It is also useful in preventive and corrective maintenance, as it helps identify abnormal pressure variations that may indicate blockages, leaks, incorrect settings, pump wear or problems in the supply line. In this sense, the pressure gauge is not only a reading accessory, but also a support tool for system diagnostics and management.

For correct use, the gauge should be installed in an easily visible position, impacts on the glass and instrument body should be avoided, the indicated maximum pressure range should not be exceeded and the connection should be checked periodically for leaks. During system cleaning operations, dried residues, deposits or incompatible products should be prevented from affecting the passage or damaging the connection. If the pointer shows abnormal movement, excessive vibration or inconsistent readings, the condition of both the circuit and the instrument should be checked.

The ASTURO 400 bar pressure gauge with glass is therefore an essential accessory for pressure control in coating systems and high-pressure pumps. With its analogue scale up to 400 bar, psi reading, protective glass and compact structure with lower connection, it allows technicians and operators to monitor the circuit quickly, clearly and efficiently, contributing to system safety, flow stability and final application quality.
