The Novus TxBlock USB is a head-mounted temperature transmitter known for its versatility and simple configuration. Its universal input accepts a wide range of temperature sensors, including various RTDs (PT100, PT1000, NTC) and thermocouples (Type J, K, T, E, N, R, S, B), as well as mV signals. The standout feature is the built-in micro-USB port, which allows for direct connection to a PC or smartphone for quick and easy programming without the need for a proprietary interface. This reduces commissioning time and simplifies maintenance, while its robust design ensures reliable 4-20mA output.
The TxBlock-USB is a compact and highly versatile head mounted temperature transmitter that stands out for its unique, user-friendly configuration method. It’s a loop-powered, 2-wire device designed for signal conversion from a wide range of industrial sensors into a standard 4-20mA output. Its core strengths lie in its universal input capabilities and the simplicity of its setup, which make it an excellent choice for a variety of applications and for simplifying spare parts inventory.
