Casi di studio

How POLWAX instruments solve typical measuring tasks – from sterile manufacturing to greenhouse farming.

These are example projects that show typical applications. They do not describe specific customers, and no measured results are claimed.

Pharmaceutical · Sterile manufacturing

Pressure cascade monitoring for a sterile filling suite

Progetto di esempio

Challenge

A sterile filling suite with Grade B, C and D areas relied on manual magnehelic readings twice per shift. Pressure reversals during material transfer went unnoticed until the next round, and paper records were hard to review for audits.

Soluzione

DPT20 differential pressure transmitters were installed on the room-to-room boundaries – buzzer versions where staff need a local alarm, 4–20 mA versions where the value goes to the BMS – with DPT30 relay versions on the airlocks. The BMS records the pressure trend for each grade.

Pharmaceutical distribution · GDP

Temperature mapping of a 6,000 m² GDP warehouse

Progetto di esempio

Challenge

A distributor had to map summer and winter conditions of a high-bay warehouse before qualification. Loggers had to cover all rack levels, dock doors and the AHU zones and deliver an auditable report.

Soluzione

CLIMA WiFi dataloggers were placed in a three-level grid across the racks and near the docks, and the data were collected in CloudDASH360 for both seasons. Warm and cold spots, for example near dock doors, show up in the combined data before qualification.

Vaccines · Cold chain logistics

Shipment monitoring for vaccine distribution

Progetto di esempio

Challenge

Vaccines are shipped at +2 … +8 °C to regional stores. Receivers needed a fast accept/reject decision on arrival, and freezing – which destroys many vaccines – had to be detected even when the logger was not read out.

Soluzione

Every shipper carries a PTRANS single-use datalogger (PDF report via USB) and a PolSENSE freeze indicator. Receivers check the indicator and the PDF report at the dock.

Commercial building · Offices

Demand-controlled ventilation for an office campus

Progetto di esempio

Challenge

Meeting rooms were ventilated at full rate all day, wasting fan and heating energy, while some rooms still exceeded 1,500 ppm CO₂ during long meetings.

Soluzione

CD50 CO₂ transmitters and ClimaTRANS RHT100 units were installed in the meeting rooms and connected via RS485 Modbus RTU to the BMS, which modulates the VAV dampers according to CO₂ and humidity.

Water utility · Pumping station

Condition monitoring of raw-water pumps

Progetto di esempio

Challenge

A pumping station had two unplanned pump failures in a year. Route-based vibration measurements every three months were too infrequent to catch developing bearing damage.

Soluzione

VibeSENSE P100 smart vibration sensors were mounted on the drive-end bearings of six motor-pump sets. Their velocity and acceleration values (4–20 mA, 0–10 V or RS485, depending on version) go to the plant’s monitoring system, which trends them and raises alarms at limits set by the maintenance team.

Agriculture · Greenhouse

Climate and light monitoring for a greenhouse farm

Progetto di esempio

Challenge

A greenhouse grower controlled shading and irrigation by fixed timers. Cloudy days caused under-lighting, sunny days heat stress.

Soluzione

A PLXWS800 integrated weather station on the roof and PAR50 sensors at crop level now feed the climate computer. Shading and irrigation are controlled by measured PAR and radiation instead of timers.
