The ALTA Wireless Thermocouple Sensor is available with a hardwired thermocouple or K-type connector to support various thermocouple types and ranges. The hardwired thermocouple option measures temperatures up to 400°C (752°F). The K-type connector with Probe includes a needle probe that measures temperatures up to 400°C (752°F). The sensor is programmed to sleep for a user-given time interval (heartbeat) and then wakeup, send power to the thermocouple and wait for it to stabilize, and convert the analog data, mathematically compute the temperature and transmit the data to the gateway. This industrial sensor features a solar cell with rechargeable battery.
