Point Sensor Analog 900 900 MHz Transmitter Main Features

Description: The Point Sensor Analog 900 wireless transmitter is a battery operated 12-bit analog-to-digital converter with a microprocessor controlled 900 MHz. FCC certified radio transmitter. The Point Sensor Analog 900 has an on board time of day clock that allows it to spend most of the time in a low power quiescent state. At predetermined time intervals the clock will wake up the onboard microprocessor and analog data is read from a 12-bit analog-to-digital converter. This information is combined with a unique serial ID number, a CRC-16 error check and transmitted in a very short data packet that results in a very short transmitter on time. This architecture allows the Point Sensor Analog 900 to consume very little energy and a battery life of up to 2 years. The Point Sensor Analog 900 electronics are coated with a conformal material that provides a moisture barrier against condensation. Submersion in water is not recommended. An internal reed switch permits a user to activate the service switch with a magnet. A quick swipe of a magnet across the “Service” label will activate the service switch. When you perform this operation, a data transmission occurs immediately and a special mark is introduced in the ID field of the transmitted data packet to indicate which sensor is in service or installation. The Sensor is shipped with the transmitter turned off (anytime the Sensor is to be shipped the transmitter should be turned off or must be placed in a shielded container to prevent interference that might cause shipping problems). The sensor is started by sliding the On/Off Switch towards the SMA antenna connection. The Point Sensor Analog-900 sensor can be turned off by sliding the On/Off switch away from the SMA antenna connection. Technical Features:
