Ace Instruments Differential Pressure Indicator DP1-LCD 24V LCD

Description

Product Overview

The Ace Instruments DP1-LCD is a precision‑engineered differential pressure indicator designed for demanding applications where reliability and accuracy are paramount. Featuring an integrated high‑speed differential pressure sensor, the unit measures pressure differentials from –180 to 180 Pascals with a tight tolerance of ±0.5% of full scale. The LCD display presents real‑time readings in a clear, easy‑to‑read format, eliminating the need for auxiliary instrumentation and reducing operator error. The device operates on a standard 24 V DC power source, making it compatible with most industrial and medical power supplies while maintaining low power consumption for extended service life.

Construction of the DP1-LCD combines a powder‑coated mild steel back housing with a stainless‑steel front flush plate, delivering a robust, corrosion‑resistant enclosure that can withstand the rigors of continuous use in harsh environments. The instrument’s compact dimensions—100 mm × 90 mm × 30 mm—allow for easy integration into existing panels or mounting on process equipment without sacrificing performance. A maximum over‑pressure rating of four times the rated pressure provides an additional safety margin, protecting both the sensor and the user from unexpected pressure spikes.

Communication capabilities are built into the design through an isolated RS485 Modbus interface, enabling seamless integration with supervisory control and data acquisition (SCADA) systems, programmable logic controllers (PLCs), and other digital monitoring platforms. The isolated protocol ensures signal integrity even in electrically noisy environments, while the Modbus standard simplifies configuration and data exchange across a wide range of devices. Two 4 mm stainless‑steel hose nipples on the rear of the unit provide secure, leak‑free connections for air or non‑corrosive gases, supporting flexible installation in a variety of process lines.

Beyond its core measurement functions, the DP1-LCD includes built‑in high and low buzzer alarms that activate when the measured pressure exceeds user‑defined set points. An acknowledgement key allows operators to silence the alarm after confirming the condition, ensuring that critical alerts are not missed while avoiding unnecessary disruptions. The alarm system is fully configurable via the Modbus interface, allowing remote adjustment of thresholds and alarm parameters to match specific process requirements.

Each DP1-LCD unit ships with a calibrated power adaptor, a comprehensive instruction manual, and a factory‑issued calibration certificate that complies with NABL standards. This complete package ensures that the instrument is ready for immediate deployment, reducing downtime and simplifying the commissioning process. The calibration certificate provides traceability to national standards, giving confidence in the accuracy and repeatability of measurements over the instrument’s service life.

Designed with both industrial and medical environments in mind, the DP1-LCD meets stringent hygiene and safety standards required for infection control rooms, hospital operating theatres, and clean‑room facilities. Its stainless‑steel front plate can be easily cleaned and disinfected, while the sealed sensor compartment prevents contamination from external sources. The device’s reliability, ease of use, and compliance with industry standards make it a versatile solution for a broad spectrum of pressure monitoring applications.

Usage

The DP1-LCD excels in environments where precise pressure differentials must be monitored continuously. In hospital operating theatres, the instrument provides real‑time feedback on ventilation and filtration systems, helping maintain optimal air quality and preventing the spread of airborne contaminants. Its compact form factor allows it to be mounted discreetly on wall panels or equipment racks, preserving valuable space while delivering critical data to surgical staff.

In industrial settings, the DP1-LCD is ideal for monitoring air or gas flow in HVAC systems, clean‑room environments, and process pipelines that handle non‑corrosive gases. The RS485 Modbus communication enables integration with existing plant monitoring networks, allowing engineers to track pressure trends, set alarms, and generate reports without manual data collection. The device’s robust construction ensures reliable operation even in facilities with high vibration, temperature fluctuations, or exposure to chemicals.

For research laboratories and quality‑control labs, the DP1-LCD offers a dependable platform for experiments that require precise pressure differentials, such as filter efficiency testing or gas permeability studies. The LCD display provides immediate visual confirmation of pressure values, while the alarm function alerts researchers to deviations that could affect experimental outcomes. The instrument’s ease of calibration and traceable certification simplify compliance with regulatory standards and internal quality protocols.
