Product Description Product DescriptionModel APTSS-20 Wireless Pressure Transmitters are developed from Heavy-duty Pressure Transmitter for remote wireless applications. In hazardous conditions or places where there is no power supply available, this APTSS-20 is useful and finds many applications, e.g., in oil wells of explosive gas or at places which are either dangerous to people or no power supply available to access. To fit to such the application, the housing of APTSS-20 is sealed tightly to meet the requirements for explosion proof of Exd IIC T5 Gb, Exia IIB T4 Ga and for environment protection of IP66.In order for different remote distances and data transmission rates, model APTSS-20 is manufactured to have different communication protocol, like LoRa (Long Range) or Zigbee, for wireless communication. LoRa is one of LPWAN (low-power wide-area-network) protocols, and is suitable for communication of a longer distance (up to kilometers). Zigbee on the other hand is suitable for communication of a shorter distance (a few hundred meters).To fit various pressure media, three types of pressure port (type-A, -B and -C) are available. Type-A (so-called inner cavity) has its pressure diaphragm located inside the port. This type of pressure port is designed to measure gases or dilute liquids. Type-B (so-called flush diaphragm) has its pressure diaphragm in front of the pressure port and is suitable for measuring viscous fluids, fluids with particles or paste, so that the pressure medium can be flush-washed away from the surface of the diaphragm. Type-C (so-called tri-clamp) has no thread and can be connected via a clamp. This type of pressure port is designed for application in either pharmaceutical or food industries.

The pressure medium should be compatible with wetted parts material and pressure diaphragm.2. For customized pressure ranges, consult Atechsensor.3. "fs" refers to full scale pressure or rated pressure.4. Communication frequency of LoRa is 433kHz while that of Zigbee is 2.4GHz.5. Accuracy = sqrt (non-linearity2 + hysteresis2 + repeatability2).6. AA batteries of 19Ah total capacity are employed.7. Calculated as a rate of output change between -10°C and +70°C or between 0°C and 50°C, and normalized by the output at 25°C.
