Battery-operated high-precision digital pressure gauge CPG1500

Recently, the demand for mechanical measuring instruments on-site has been shifting towards instruments equipped with wireless units for field instructions and data transmission. These instruments often come with long-lasting batteries and are frequently installed in explosion-proof areas. In such environments, two types of explosion-proof designs, Ex i or Ex d, are generally preferred. For pressure gauges and other measuring instruments, these are electrical devices that must be suitable for the atmosphere according to the relevant approvals. Intrinsic safety explosion-proof design completely prevents the equipment from igniting explosive atmospheres, and the values of power, current, and voltage are kept low accordingly. Furthermore, there is a possibility that ignition sources may exist within the instrument itself. Therefore, the housing must be designed to be explosion-proof, ensuring that any potential explosion does not leak to the outside. WIKA's pressure measuring instruments with battery operation and ignition protection type Ex i, such as the high-precision digital pressure gauge model CPG1500 and the Bourdon tube pressure gauge model PGU, along with the wireless unit model NETRIS3, have many installation records in environments like the one described above.

The procedures and documentation for hydrostatic pressure testing can be made more efficient by using digital pressure gauges. In particular, models CPG1500 and CPG1200, which feature Bluetooth data transmission capabilities, can greatly contribute to improving work efficiency. In hydrostatic pressure testing, it is often necessary to have a portable device consisting of a pressure generating unit and a measuring instrument for the test pressure. The equipment shown in the photo is permanently installed in the pressure generation unit. The large display with a backlight allows for clear readings even in poor lighting conditions. The display of measurement values with two to three decimal places enables immediate recognition of whether the test pressure is constant or if pressure loss indicates a leak. The main advantage of WIKA digital pressure gauges is their suitability for documentation. Equipped with data logger functionality and a Bluetooth interface, they can seamlessly record test sequences both numerically and graphically using dedicated software. With WIKA-Cal software, all data can be wirelessly transferred to a notebook immediately, making it easier than ever to create test reports.

The digital pressure gauge model CPG1200 allows for convenient and flexible setting of operating pressure, readjustment of pressure switches, and pressure monitoring (such as leak tests during transport). Designed for battery operation, it is particularly suitable for mobile applications. Its durable plastic case and optional protective case cap make it very robust, easily withstanding vibrations and impacts during use. Proven measurement technology covers a general range from -1 to 1,000 bar (gauge pressure) with an accuracy of less than 0.25% FS. The measurement frequency can be set to 1, 3, 4, or 10 times per second, depending on requirements. The CPG1200 also features an energy-saving mode. In practice, it can operate for up to 4,000 hours without needing to replace the battery. As an option, it can be equipped with a built-in data logger that can store up to 1 million data points. The saved measurement data can be read via the built-in USB interface, which also powers the device. Wireless transmission via Bluetooth is also possible.

Pressure monitoring inside transport tanks is very important in the pharmaceutical industry to ensure there are no leaks from the containers during transport, especially when it comes to active ingredients. Since pharmaceutical active ingredients are expensive, pharmaceutical companies take every possible measure to avoid losses. This applies to both the manufacturing process and transport, where the empty space inside the transport tank is always covered with inert gas to protect the pharmaceutical components. Monitoring the pressure inside the tank during transport extends to this space. The internal pressure in this space must remain constant, and if the pressure drops, it raises suspicions of leaks in valves or seals. With WIKA's PG43SA series of two diaphragm pressure gauges, it is possible to prevent cost losses, leaks, and contamination risks due to transport tank issues. The general advantages of diaphragm pressure gauges include high overload safety and the fact that the measuring cell is dry, eliminating the risk of medium contamination. Furthermore, the PG43SA has a hygienic design with the diaphragm element welded in the same plane as the front, making it suitable for CIP/SIP cleaning processes and capable of autoclave sterilization.
