AMS 4516 – pressure transmitter with a Bluetooth LE 5.1 signal
AMSYS – Gateway for bluetooth sensors
The miniaturized sensors in the AMS 4516 series are high-precision, ready-to-use transmitters* which are suitable for measuring absolute, relative and differential pressure. They transmit measurement data via Bluetooth Low Energy 5.1 (BLE; radio frequency of 2.4 GHz). The sensors are optimized for low power consumption and operated by a single cell battery (CR 2032). They have a free-field range of approximately 100 m (328 ft). The sensors can be read out and configured using the AMS 4516 Android app, the AMSYS-gateway or a windows desktop application.
The offset and span are electronically calibrated and the temperature-related offset and span drift compensated for during manufacture, so that no subsequent calibration by the user is required. The wireless pressure transmitters are supplied in a compact, robust plastic package (IP44) for quick screw mounting and are suitable for external installation.
Thanks to Underside pressurization* the pressure transmitters are media resistant on one side and come in several different versions for a wide pressure range of 5 mbar to 1 bar.
Variants of AMS 4516
AMS 4516 low pressure ranges, differential and bidirectional differential:
0–5 and 0–10 mbar; ±5 and ±10 mbar
AMS 4516 low pressure ranges, differential/relative and bidirectional differential:
0–50 and 0–100 mbar; ±25, ±50 and ±100 mbar
AMS 4516 standard pressure ranges, differential/relative:
0-200; 0-350; 0-500 and 0-1000 mbar; ±200; ±350; ±500 and ±1000 mbar
A barometric version from 10-2,000 mbar is available as AMS 4506
Please note: AMS 4516 sensors can also be custom-calibrated and the AMS 4516 app specially adapted.
Further variants in the transmitter family include the wired AMS 4711 with a 5-V output, the AMS 4710 with a 10-V output or the AMS 4712 with an interference-resistant 4–20 mA current output. The AMS 3011 in its robust metal package with a 5V output can also cope with high system pressures*.
Newly available is the AMSYS Gateway. A linux-based RPI3b+ device with an integrated ssh-server, working as an interface between the Bluetooth pressure sensor and the local network. Especially when using several Bluetooth sensors, the gateway makes it easier to keep an eye on the real-time results of the sensors and to handle the data.
