Cost-effective digital temperature logging module for the RS232 and USB interface for sensing devices with temperature resistance sensors



The DTM5080 temperature-logging module is simply inserted into the serial RS 232 interface of a PC. For use of the computer’s USB connection a variant with a USB adapter can be obtained (specify on ordering). It is suitable for the logging of temperature resistance sensors such as Pt100/1000, Ni100/1000, as well as other resistance sensors up to a maximum value of 2.5 k. The corresponding temperature or resistance value is outputted. The data-logging program that is also supplied validates the measured values and stores them as required. By means of control via simple ASCII characters data logging using programming languages such as C or Visual Basic is also not a problem. The module stands out primarily in terms of its very high accuracy, simplicity of operation, and a very favourable price. It has been designed for accurate measurements over a wide range of temperatures. When the sensor is connected up using 4-lead technology a high overall accuracy of the device can be achieved when used in conjunction with a high-precision sensor. The resolution of the device is 0.01°C.
The DTM5080 temperature-logging module is supplied with a standard Pt100 cable sensing device, Class B, 3.5x30mm, 1m cable, and a 2m extension cable for the RS 232 interface or a USB adapter cable. For particular measurement problems we can also manufacture cost-effective, customer-specific sensing devices to your specifications.
