Preserving accurate differences in pressure is essential in controlled-environment testing, whether in gloveboxes, chambers, cleanrooms, or environmental test enclosures.ย The 90001848 Differential Low Pressure Sensor from Electro-Tech Systems is designed to work in combination with their M-5300 Series EnviroPro PLC controllers to provide constant, dependable, and highly accurate chamber pressure monitoring.

A sealed glovebox or dry-gas dehumidification system may experience different gas distribution because of even small pressure changes.ย In pharmaceuticals, semiconductor manufacturing, materials research, and biological settings, this mismatch can lead to moisture gradients, chemical irregularities, and eventually jeopardize test findings.ย ETS understands that maintaining a stable surroundings needs more than just controlling temperature and humidity; controlling pressure is as important.

When combined with ETS’s EnviroPro controller system, the sensor gains extra power.ย These upscale units consist of:
- Control of programmable PID logic
- Flexible communication: Ethernet for remote datalogging and monitoring, RS-232, and RS-485
- Digital interface or touchscreen for status and setup
- Alarm thresholds connected to the sensor’s pressure readings
This combination ensures consistent, reproducible testing conditions by providing engineers and technicians with exact control over pressure, and therefore, humidity and temperature.

A variety of fields are supported by ETS pressure sensors and controlling systems:
- Materials science rooms where a consistent dry-gas flow is required
- Pressure gradients in semiconductor cleanrooms can have an effect on contamination control
- Enclosures used for pharmaceutical manufacture that must conform to high environmentalย ย standards
- Gloveboxes for sensitive research, moisture-critical tests, and electrostatic testing settings in laboratories

There is not much work involved in installing the ETS 90001848 pressure sensor.ย It uses either the Micro-USB (for power/data) or the quick-lock connector to connect to the EnviroPro controller.ย In typical lab settings, maintenance is essentially nonexistent and is regarded as maintenance-free.
ETS provides calibrated service support and RMA processes through their Perkasie, Pennsylvania-based service staff in the event that repairs are required.

Common problems like “no power” or “no pressure reading” are typically caused by malfunctioning power connectors or incorrectly configured controllers, according to the troubleshooting advice provided by ETS.ย Matching the sensor with approved ETS hardware lowers integration complexity and support costs because it is only compatible with the Mโฏ5300 series EnviroPro system.

- Pair the ETS sensor with a compatible Mโฏ5300 EnviroPro controller to leverage realโtime logging and alarms.
- Configure threshold alarms so that deviationsโhowever subtleโare flagged immediately.
- Ensure power wiring (12โ30โฏVDC) is correct and secure, including tight connection of the quickโlock aviation plug.
- Use calibration services through ETS: their ISOโฏ17025 lab can validate sensor accuracy periodically.
- Leverage data logging features from the controller to analyze trends, validate performance, and document compliance for regulated environments.

Imagine a research lab that has to use dry gas purging to keep an enclosed test globe at a very low moisture level:
- It need accurate pressure monitoring to make sure gas is arriving at the right differential pressure; airflow control alone is insufficient.
- An EnviroPro PLC is connected to the 90001848 sensor, which provides continuous input and sounds an alert if the pressure deviates from allowable bounds.
- This guarantees test integrity and constant humidity removal, which is crucial when sample humidity needs to stay within strict parameters.
