SS316L IP65 Waterproof Sensor Pressure Temperature

The industrial sensing landscape increasingly relies on robust instruments capable of withstanding aggressive media and washdown procedures. Within our precision lineup, the 0.5-4.5v IP65 Waterproof Sensor Pressure Temperature variant offers a ratiometric output ideal for battery-powered embedded systems. For applications demanding intrinsic corrosion resistance, the core platform is also reflected in the dedicated SS316L Material Pressure Temperature Sensor build, which uses fully welded wetted parts to eliminate elastomer failure points. Systems integrators balancing long cable runs against electrical noise frequently standardize on the 4-20ma Output Presion Sensor Pressure Temperature loop-powered configuration. In parallel, laboratory and IoT environments looking to bypass analog-to-digital conversion overhead benefit directly from the raw data stream of the I2C Digital Output Presion Sensor Pressure Temperature interface. Each output variant shares a common mechanical footprint and environmental sealing philosophy, ensuring consistent interchangeability across complex test benches and field installations.

The SS316L IP65 Waterproof Sensor Pressure Temperature is engineered as a dual-parameter node that measures media pressure and temperature simultaneously through a single process connection. The sensing element utilizes a silicon piezoresistive die oil-filled and isolated behind a flush 316L stainless steel diaphragm, while a platinum RTD element is bonded adjacent to the diaphragm for rapid thermal equilibrium. All wetted components, including the housing, hex drive, and pressure port, are machined from vacuum-melted 316L bar stock with a surface roughness below Ra 0.8 µm certified by 3.1 material traceability. Electrical termination is achieved via an M12 circular connector with gold-plated contacts, and the internal electronics cavity is potted under vacuum to eliminate moisture ingress during thermal cycling. The following technical specifications define the standard product range.
