Measuring transducer for temperature, input NiCr-Ni-type K thermocouple 1 2 Straightforward application Suitable for severe operating conditions Compact construction Galvanic isolation between sensor input and Measuring Transducers output signal to the operating voltage • Provision made for fine adjustment of measuring range Anti-tamper seal for the fine adjustment Meet high EMC-requirements Short-circuit-proof output selectable from Reference junction for temperature compensation integrated Broken-wire monitoring of input signal Operating characteristics displayed by integrated LED Flame-inhibiting and self-extinguishing body Suitable thermocouples are available Measuring transducers of series 5 Measuring transducers of the Series 5 are designed to convert electric input values into standardised output signals. Principle of operation: The transducer signal measured at the converter input is converted into a standardised output signal that is proportional to the input and lends itself to further customised processing, for instance, in a machine controller. General notes on Type VTK5.. Description VTK5.. The Type VTK5.. is measuring the temperature dependently voltage of a NiCr-Ni-type K thermocouple according to EN60584-1. The for temperature measuring with thermocouples needed reference junction is integrated in the measuring transducer. No external reference sensor is required. For satisfactory working of the device, it is necessary that the compensating line be extended to the transducer. Electric isolation Output signal The output signal generated is a standardized voltage of 0 ... 10 V/DC or 2 ... 10 V/DC, respectively, a standardized current of 0 ... 20 mA or 4 ... 40 mA. The output signal follows the input signal proportionally. The output signal can be used to supply additional devices, such as indicating instruments and limit-value switches. Point to be noted: the maximum driver capability of the output. Monitoring for integrity Sensor input and output signals are electrically isolated from The devices come equipped with sensor monitoring for sensor- the operating voltage. Multiple operation of amplifiers and evaluation lead breakage. In the event of any fault, the output signal setting is devices is therefore possible at the same operating voltage. The sensor only supplies one amplifier device. Operating status display by LED The green LED will be lit when the operating voltage is applied and the device is working normally. In addition to the fault signal, it will be flashing to sig
