METPOINT DPM SD23 with BDL compact 4031322

Overview

The BEKO METPOINT DPM SD23 dew point transmitter is a pressure dew point instrument designed for continuous measurement of moisture in compressed air and technical gases. Combined with the BDL compact data logger, it forms a complete measurement and documentation station for compressed air quality monitoring.

With a measuring range of -60 to +30 Ctd and outputs in both 4-20mA and RS485 Modbus, the SD23 integrates directly with process control systems and data acquisition networks. The BDL compact data logger adds a 3.5-inch touch screen display, trending, and data recording capability for on-site analysis.

Engineering & Design

The SD23 transmitter is supplied with a desiccant sleeve and a MK-Basic-PN16 measuring chamber, allowing installation directly in the compressed air line at operating pressures up to 50 barg. The 4-wire 4-20mA output provides a standard process signal, while the RS485 Modbus interface enables digital communication with PLC and SCADA systems.

The BDL compact data logger is housed in a compact 180 x 166 x 115 mm enclosure with a TFT transmissive touch screen, operating from 0 to +50 C, and is powered from 100 to 240 VAC. A lithium chloride 11.3% calibration set is included for pressure dew point verification.

Specifications

Compressed air quality programmes depend on repeatable measurements, and the METPOINT DPM SD23 dew point transmitter is engineered for that purpose, which is why Seven Star LLC supplies the METPOINT DPM SD23 dew point transmitter with the BDL compact data logger as a complete measurement station.

Why Seven Star LLC

Seven Star LLC supplies the BEKO METPOINT DPM SD23 dew point transmitter and BDL data logger for compressed air quality projects across the Gulf, with full documentation and technical support. Our team assists with installation planning, output configuration, and integration into existing monitoring systems.

We support compressed air and gas quality measurement programmes in industrial plants, providing genuine BEKO products and responsive after-sales service.

Measurement Confidence

The SD23’s -60 to +30 Ctd range covers the dew point levels expected at dryer outlets and distribution headers, and the RS485 Modbus output allows the readings to be collected automatically by plant systems without manual rounds. The 4-20mA output provides a continuous process signal for control room display.

The included lithium chloride calibration set supports on-site verification, while the desiccant sleeve and MK-Basic-PN16 chamber protect the sensor from contamination. The BDL compact logger records the measurement history needed for quality audits and dryer performance reviews.

Documentation & Supply

Seven Star LLC supplies the METPOINT DPM SD23 with complete documentation and configuration guidance, supporting your compressed air quality monitoring project from selection to commissioning.

Our team also supports BEKO accessories, spare chambers, and calibration consumables across the Gulf region.

Routine dew point verification is part of any compressed air quality programme, and the complete METPOINT package reduces the effort: the SD23 provides the continuous measurement and the BDL logger stores the record, while the included calibration set supports the periodic checks that auditors expect.

Compressed air quality teams choose the METPOINT DPM SD23 dew point transmitter for its proven performance. Seven Star LLC supplies the SD23 together with the BDL logger, so it is available as a complete package for your monitoring programme.

For plants standardising their monitoring hardware, the METPOINT DPM SD23 dew point transmitter is the reference choice, and Seven Star LLC keeps the METPOINT DPM SD23 dew point transmitter available with the BDL compact.

Installation and Commissioning

The measuring chamber supplied with the SD23 lets the sensor sit in a controlled sample stream taken from the compressed air line. Take the sample from the top of the pipe, downstream of the dryer and filters, and keep the connection short so the reading reflects the air actually delivered to users. Before start-up, check that the line pressure at the tapping point stays within the rating of the transmitter and chamber.

• Wire the 4–20 mA output and the RS485 Modbus line to the BDL compact or to the plant control system as required.
• Configure the logger channels, alarm limits and logging interval to match the air quality class the plant needs to demonstrate.
• Allow time for the sensor to dry down after installation before the first reading is accepted.

Data Logging and Integration

Many plants use the METPOINT DPM SD23 dew point transmitter together with the BDL compact as a standalone quality station, reviewing trends on the touch screen and exporting records for audits. Where a central system exists, the Modbus interface allows the same dew point value to be read by a PLC or SCADA system, so alarms reach the control room as well as the local display.

Verification and Maintenance

The included lithium chloride calibration set allows a quick check of the sensor at a known reference point between laboratory calibrations. A sharp rise in dew point normally points to the dryer or a drain rather than the sensor, so check regeneration, drains and filters first. Replace the desiccant sleeve when it becomes saturated.

Compressed Air Quality in Oman and the GCC

Hot, humid coastal conditions in Muscat, Sohar and Duqm put refrigeration and desiccant dryers under constant load, and moisture in instrument air quickly damages valves, positioners and pneumatic tools. Food, pharmaceutical and electronics plants also need documented air quality. Seven Star LLC supplies BEKO METPOINT measurement sets and can help match the transmitter and logger configuration to your air system.
