Paperless Recorders with colored TFT display
Paperless recorder is an electronic device in protection housing with colored TFT screen and membrane keyboard to measure, display and record different physical quantities: temperature, humidity, gas concentration, consumption, etc. Also, paperless recorders can record and display incoming discrete signals to inputs of dry contact type, and to generate alarm signal to relay outputs.
It can operate as a part of network of devices by RS485 interface or Ethernet (T-bus protocol). Paperless recorder uses built-in non-volatile flash memory of 2 Mbyte. That's why it doesn't need the constant connection with a PC, unlike the most recorders operating on RS485 network. It transfers data by the network by a request or automatically by specified response time. Also, flash memory ensures save data in case of power supply corruption on RS485 network or on PC. Paperless recorders are replacement of obsolete paper recorders, because there are no mechanical parts, that wear out, and supplies. It also can scale automatically analogue input signals in any convenient unit of measurement.
