Stainless Steel Four-Wire Huatian Standard Package Hydac Pressure Transmitter Sensors

Product Description

Product Description The sensor can transfer the measurement signals of temperature, pressure and liquid level to I2C digital output. With the fast and accurate interface, the sensor is used to build an Internet of Things using a microcontroller. It can read data and control power on and off to reduce power consumption through microprocessor operation. Features Digital compensation for sensor offset, sensitivity, temperature drift and nonlinearity 32-bit customer ID field for module traceability Digital output of temperature and pressure in I2C bus mode Fast power-on to data output response: 3ms Low power consumption, sleep mode operation, as low as 5 μ A, current consumption depends on the programmed sampling rate Operating temperature: -40°C to + 85°C Wide supply voltage capability: 3.3V/5V Technical Index
