Industrial Analog and Digital Output Temperature Sensors are designed to?measure the amount of ambient heat energy. The characteristics are sensor type, sensing temperature local, sensing temperature remote, output type, voltage supply, and resolution. The sensor types are analog local/remote/infrared, analog-digital, local/remote, digital local/remote/infrared, or internal, with a sensing temperature range of -55°C to 200°C. These are made for use in an industrial setting.
