A digital pressure gauge is an electronic instrument used to measure and display pressure accurately in numerical form. The applied pressure acts on an internal pressure sensor, which converts the pressure into an electrical signal. This signal is processed by the instrument’s electronics and displayed on a display in the selected pressure unit. Digital pressure gauges provide higher accuracy, better readability, and additional functions such as unit conversion, Min/Max recording, and zero correction compared to conventional analog gauges.

Vijay Enterprises digital pressure gauges are designed to provide reliable and repeatable pressure measurement for industrial, hydraulic, and pneumatic applications. Each digital pressure gauge utilizes a precision electronic pressure sensor that converts applied pressure into an electrical signal, which is processed through calibrated electronics and displayed on a high-resolution digital display. All instruments are calibrated using traceable reference standards to ensure measurement accuracy across the specified pressure range. This ensures dependable performance in applications such as hydraulic testing, compressor monitoring, process industries, and equipment maintenance.

Vijay Enterprises manufactures digital pressure gauges in multiple accuracy classes to suit different pressure measurement requirements. Standard models are available with accuracies such as ±0.25% F.S., ±0.1% F.S., ±0.05% F.S., and ±0.025% F.S. suitable for general industrial monitoring, testing applications, and as calibration masters. Selection of accuracy depends on application criticality, whether for routine pressure monitoring, laboratory testing, or calibration verification. Our team assists customers in selecting the appropriate accuracy level based on operating conditions and process requirements.

Vijay Enterprises digital pressure gauges are available for different pressure reference types depending on application requirements: • Gauge Pressure Measurement – Used in most industrial and hydraulic applications where pressure is measured relative to atmospheric pressure. • Absolute Pressure Measurement – Used in scientific, vacuum, and specialized process applications requiring reference to absolute zero pressure. • Vacuum Measurement – Suitable for systems operating below atmospheric pressure. Correct selection of pressure reference ensures accurate monitoring and process reliability across industrial environments.

Vijay Enterprises manufactures reliable pressure calibration sources designed for generating controlled pressure during the testing and calibration of pressure measuring instruments. Our product range includes both pneumatic and hydraulic pressure calibration pumps to cover a wide range of calibration applications. For low and medium pressure applications, we manufacture pneumatic pressure sources capable of generating vacuum and positive pressure from -1 bar to 40 bar, depending on the model. These include: • Pressure Comparator (-1 to 10 bar) – commonly used for precise low-pressure calibration and comparison testing. • Scissor-Type Hand Pump (-1 to 40 bar) – designed for generating higher pneumatic pressures with fine control during calibration procedures. • Screw-Type Pressure Pump – suitable for low-pressure and vacuum applications requiring stable and precise pressure generation. For high-pressure calibration requirements, Vijay Enterprises manufactures hydraulic pressure comparators capable of generating pressures up to 1000 bar. These instruments are widely used for calibrating high-pressure gauges, transmitters, and other pressure instruments used in hydraulic systems and industrial equipment. Vijay Enterprises pressure calibration pumps are commonly used for calibrating digital pressure gauges, analog pressure gauges, pressure transmitters, and pressure switches in calibration laboratories, instrumentation workshops, maintenance departments, and industrial testing environments. Our pressure sources are widely used by instrumentation engineers, calibration laboratories, maintenance teams, and testing facilities that require reliable, stable, and repeatable pressure generation for accurate calibration work

Yes. Vijay Enterprises pressure sources are specifically designed for pressure gauge calibration and testing applications. They provide controlled and stable pressure generation required for comparing a test gauge against a reference standard. These pressure calibration pumps are commonly used in instrumentation workshops, calibration laboratories, manufacturing facilities, and maintenance departments to verify the accuracy of pressure measuring instruments. When used together with a master digital pressure gauge or pressure calibrator, Vijay Enterprises pressure sources provide an effective solution for reliable pressure calibration.

The main difference between pneumatic and hydraulic pressure sources lies in the pressure medium and pressure range they can generate. A pneumatic pressure source uses air or gas as the pressure medium and is typically used for low-pressure calibration applications, such as testing pressure gauges, transmitters, and switches operating at lower pressure ranges. A hydraulic pressure source uses liquid, usually oil or water, and is capable of generating much higher pressures. Hydraulic pressure comparators are commonly used for testing and calibrating high-pressure gauges used in hydraulic systems and industrial equipment. Selecting the appropriate pressure source depends on the required pressure range and the type of instruments being calibrated.

Yes. Vijay Enterprises pressure calibration pumps are designed to be compact, lightweight, and portable, making them suitable for both laboratory calibration and on-site field testing. At Vijay Enterprises, we focus on manufacturing pressure sources that are easy to use, transport, and operate in real industrial environments. This allows engineers and technicians to conveniently carry the equipment to industrial plants, maintenance locations, and testing facilities where pressure instruments need to be verified or calibrated. For example, our hydraulic pressure comparators weigh approximately 3.5 kg, making them significantly easier to carry and use at site compared to many conventional high-pressure calibration systems. This lightweight design enables technicians to perform high-pressure gauge calibration up to 1000 bar without requiring bulky or complex equipment. Portable pressure sources are particularly valuable for maintenance teams, calibration technicians, and service engineers who frequently perform pressure gauge and transmitter calibration outside of dedicated calibration laboratories.
