Sensata Technologies PTE7300-24DM-0B100SN Pressure Transmitter, Sealed Gauge, 0-100 bar, NPTF, 5-Pin M12 Connector

The PTE7300-24DM-0B100SN is a sealed gauge pressure transmitter. It measures pressure relative to a sealed internal reference chamber (approximately 1 atm), not a perfect vacuum. This makes it suitable for applications where gauge pressure relative to ambient atmospheric conditions is required, such as in hydraulic systems or compressed air lines, but not for applications requiring absolute pressure readings like barometric sensing.

Connect the transmitter's 5-pin M12 connector to a compatible cable, mapping the I2C data (SDA), clock (SCL), power (3.3-5.5V), and ground pins to your microcontroller. Use standard I2C libraries (e.g., Wire.h for Arduino) to read the pressure data. Ensure you provide the correct supply voltage within the 3.3–5.5 VDC range and include appropriate pull-up resistors on the SDA and SCL lines if not internally provided.

The 17-4PH stainless steel housing offers good corrosion resistance against many industrial fluids, oils, and gases. However, for highly aggressive media like concentrated acids, chlorides, or saltwater, you must verify the specific chemical compatibility of 17-4PH stainless steel. For such applications, consulting Sensata Technologies's material compatibility charts or considering a sensor with an optional isolation diaphragm is recommended.

The 1/4"-18 NPTF (National Pipe Taper Fuel) thread is a dry-seal thread designed to create a pressure-tight seal without the need for thread sealants like Teflon tape, though sealant is often used for added security. Install the transmitter by screwing it into a corresponding female NPTF port, applying appropriate torque to avoid damaging the threads or sensor diaphragm. Ensure the port is clean and free of debris before installation.
