Why do the results of differential pressure sensors have large errors?

The cause may be: 1. Improper selection of the installation location, resulting in the pressure sensor is subject to lateral force. 2. Temperature gradient or unevenness exists in the pressure line, causing sensor temperature error. 3. aging or damage to the sensor.

Why is temperature compensation not effective?

The cause may be: 1. The temperature sensor is faulty or not calibrated in time. 2. Ambient temperature fluctuates greatly, exceeding the temperature compensation range. Solution: 1. Check whether the temperature sensor is working properly and calibrate it as required. 2. If the ambient temperature fluctuation is large and beyond the temperature compensation range, consider taking temperature isolation measures or using a pressure transmitter with a larger temperature range.

Key features

Integrated MEMS element paired with a proprietary conditioning chip delivers complete pressure calibration and temperature compensation using low-power, high-precision technology.

ABS model suits standard clean room and HVAC applications, while the die-cast aluminum variant withstands chemical reactor, boiler, and dust collector environments.

Die-cast aluminum model is precision assembled using stress isolation technology, minimizing mechanical stress on the sensing element to deliver stronger anti-interference and long-term stability.

Built-in auto temperature compensation function corrects for ambient temperature changes within the -5 to 65 degrees C compensation range, reducing measurement drift.

Annual stability specified at plus 0.2% FS ensures measurement consistency over long deployment periods without recalibration in clean rooms, boilers, and industrial ventilation systems.

Display variants feature dust-resistant buttons and an LCD screen allowing real-time data viewing and manual parameter modification directly on-site without a laptop or configuration tool.

ABS model uses a bottom-mounted waterproof connector with high locking strength and aging-resistant materials, maintaining a reliable sealed connection throughout long-term outdoor or industrial use.

ABS model offers both pyramid outer diameter 6mm and quick-connect inner diameter 8mm port options, while the aluminum model uses pagoda-shaped 6mm nozzles for simple push-fit tubing connections.

RS485 ABS variant draws only 0.1W, the lowest in the product line, supporting flexible DC power infrastructure from solar supplies to industrial panel feeds without voltage regulation.

Built-in circuit-level protection against reverse wiring, instantaneous overcurrent, and overvoltage meets EMI standards, reducing damage risk from common field wiring errors or power supply anomalies

AI-Powered supplier vetting

SummarySHANDONG RENKE CONTROL TECHNOLOGY CO., LTD. is identified as a Jinan-based trading company operating in manufacturing-related industries, including integrated circuits and environmental monitoring instruments. The supplier reports ISO9001:2015, RoHS, CE, and FCC certifications. It provides extensive customization and ODM services, has introduced new products within the past year, and reports OEM service for well-known brands. Production-related information includes sensor productivity of 400,000 pieces and five quality inspectors, although finished-product inspection has instructions but no written records. The supplier lacks inventory, overseas warehouses, overseas agents or branches, and a valid manufacturing-capacity contract with affiliated subcontractors. Financial records are referenced for 2022–2024, but no monetary figures or detailed financial indicators are provided. Customer evidence is limited to one associated buyer name and does not establish the scope or quality of completed projects.

CertificationsThe supplier reports an ISO9001:2015 certificate and product certifications including RoHS, CE, and FCC. These certifications explicitly support quality-management and product-compliance capability.

After-Sales capabilityThe supplier reports no inventory capability, no overseas warehouse, no overseas showroom, and no overseas agents or branches. It also reports serving zero countries overseas, so the provided evidence does not demonstrate strong after-sales coverage, particularly internationally.

R&D capabilityThe supplier reports new products within the past year, provides ODM services, and offers customization from samples, designs, and full specifications. However, it reports no available SDK, so innovation capability is supported in product development and design services but not across all technical-development resources.

Production capacityThe supplier reports sensor productivity of 400,000 pieces, five quality inspectors, and production equipment including an MST mounter and auto-soldering and soldering capabilities. Nevertheless, it has no valid manufacturing-capacity contract with affiliated subcontractors, and its inspection and supplier-assessment procedures lack written records, limiting assurance of production control.

Customization capabilityBoth reported design-service fields list customization from samples, designs, full customization, minor customization, and flexible customization. The supplier also reports ODM capability, providing explicit evidence of broad customization support.

Product Q&A

Q:What is differential pressure?

Differential pressure refers to the difference in pressure between two points in the system.

Q:What is differential pressure sensor?

Differential pressure sensor is a device used to measure the pressure difference between two objects. Differential pressure sensor is a widely used sensor in industry and science.

Q:What are some applications for differential pressure sensors?

Differential pressure sensors are widely used in textile workshop, boiler air supply, underground ventilation and other power, coal, spinning cotton box, dust removal equipment, industry pressure process control field.

Q:What should you pay attention to when installing a differential pressure sensor?

Many factors need to be considered when installing a differential pressure sensor, such as protection class, supported fluid type and flow rate range, lateral temperature gradients and zero drift due to temperature changes. For optimum measurement results, install the transducer carefully following the guidelines provided by the manufacturer.

Q:Why is the output signal unstable or fluctuating greatly?

The causes may be: 1. unstable supply voltage. 2. Improper choice of installation location and external interference. 3. There is air leakage or obstruction in the pressure line. Solution: 1. Check whether the supply voltage is stable, if necessary, use a stabilized power supply. 2. Re-select the installation location to avoid external interference, such as vibration or electromagnetic interference. 3. Check whether there is air leakage or obstruction in the pressure pipe, repair or clean.
