INSTRUKART Differential Pressure Indicator 0.5% FS 4‑Digit LED

Description

Product Overview

The INSTRUKART differential pressure indicator is engineered to meet the demanding requirements of modern industrial and scientific applications. Featuring a measurement span of -50 to +50 mm WC (or -500 to +500 Pa) it delivers reliable data across a broad pressure spectrum, making it suitable for both low‑flow and high‑flow environments. The device incorporates a high‑speed differential pressure sensor that translates minute pressure variations into a stable, easy‑to‑read 4‑digit red LED display, ensuring operators can quickly assess system performance without ambiguity.

Precision is at the heart of this instrument. With an accuracy of ±0.5% of full scale, the indicator provides confidence in critical processes such as cleanroom monitoring, HVAC system balancing, and biosafety cabinet verification. The resolution of 1 Pa (0.1 mm WC) allows for fine‑tuned adjustments, while the integrated calibration certificate guarantees traceability to recognized standards. The robust aluminium LM‑6 powder‑coated housing protects the internal electronics from dust, moisture, and mechanical impact, extending the product’s service life even in harsh industrial settings.

Connectivity options further enhance the indicator’s versatility. An optional isolated RS‑485 Modbus interface enables seamless integration with building management systems, SCADA platforms, or remote monitoring solutions. This digital communication capability allows for real‑time data acquisition, trend analysis, and automated alarm triggering, reducing the need for manual checks and improving overall operational efficiency. The instrument’s compact enclosure (75 × 70 × 40 mm) fits easily into existing panel spaces, and the included 4 mm hose nipples simplify installation with standard tubing.

Power consumption is minimized through a 24 V DC supply, delivering consistent performance while reducing energy costs. The front panel is protected by a water‑splash‑proof polycarbonate sticker, ensuring readability even in environments where condensation or occasional splashes may occur. The design also incorporates a flush bezel fitment, providing a sleek, professional appearance that aligns with the aesthetic expectations of high‑end laboratory and cleanroom equipment.

Every unit ships with a complete set of accessories: a precision adaptor for sensor connection, a detailed instruction manual, and a calibration certificate. This comprehensive package enables rapid deployment, allowing technicians to focus on system validation rather than extensive setup procedures. The INSTRUKART brand’s reputation for quality and reliability is reflected in each component, delivering peace of mind to users who demand uncompromising performance.

Usage

In pharmaceutical clean rooms, maintaining a stable pressure differential is essential to prevent contamination ingress. The INSTRUKART indicator provides continuous monitoring, alerting staff to any deviation that could compromise product sterility. Its high accuracy and quick response time make it an ideal choice for environments where even minor pressure fluctuations can have significant consequences.

HVAC engineers rely on precise pressure measurements to balance air distribution across large facilities. By installing the indicator at strategic points within ductwork, technicians can verify that supply and return air pressures meet design specifications, optimizing energy consumption and ensuring occupant comfort. The optional Modbus communication further streamlines data collection, enabling centralized monitoring across multiple zones.

Biosafety cabinets and laminar flow hoods demand strict pressure control to protect both personnel and samples. The indicator’s robust construction and clear display allow laboratory personnel to quickly confirm that the cabinet is operating within safe pressure limits before commencing work. Its ability to withstand routine cleaning procedures without degradation ensures long‑term reliability in these critical safety applications.

FAQ

What is the maximum over‑pressure the indicator can tolerate?

The device is rated to withstand pressures up to twice its maximum operating pressure, providing a safety margin that protects the sensor and internal electronics from accidental spikes.

Can the indicator be integrated into an existing building management system?

Yes. An optional isolated RS‑485 Modbus interface allows the indicator to communicate with most BMS platforms, enabling remote monitoring, data logging, and alarm configuration without additional hardware.

Is the indicator suitable for use in explosive or hazardous atmospheres?

While the indicator is designed for industrial and scientific settings, it is not certified for intrinsically safe or explosion‑proof zones. For such environments, a specially rated sensor should be selected.

How often should the indicator be calibrated?

We recommend a calibration check at least once a year, or more frequently if the instrument is used in highly critical applications. The included calibration certificate provides a baseline, and our service team can perform on‑site recalibration if needed.

What accessories are included with the product?

Each unit ships with an adaptor for sensor connection, a detailed instruction manual, and a calibration certificate. Optional accessories such as mounting brackets and extended cable assemblies are available upon request.
