AMS 4516 – pressure transmitter with a Bluetooth 4.2 signal

AMSYS Gateway for wireless sensors by AMSYS

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 4.2 (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. The sensors can be read out and configured using the AMS 4516 Android app (provided free of charge by AMSYS).

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 (IP67) 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 2 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:
0–20, 0–50 and 0–100 mbar; ±20, ±50 and ±100 mbar

AMS 4516 standard pressure ranges, differential/relative:
0–200, 0–350, 0–1,000 and 0–2,000 mbar; ±200, ±350 and ±1,000 mbar

AMS 4516 standard pressure ranges, absolute:
0–1,000 and 0–2,000 mbar

AMS 4516 barometric pressure range (absolute):
700–1,200 mbar

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 in a compact plastic package (IP67), 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 interface between the bluetooth pressure sensor and the local network. Specially 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.
