ДТ1-DN

ДТ1-DN precision temperature sensor for DeviceNet™ networks

Purpose:

• ДТ1-DN series temperature sensors measure the temperature of various media over the range -55 °C … +125 °C;
• The temperature-sensing element in the sensor is a semiconductor p-n junction, whose temperature characteristic is exceptionally stable and reproducible under cyclic temperature changes;
• The temperature sensor transmits data digitally to the control system in DeviceNet™ format;
• The DN-1 sensor can be supervised by a programmable logic controller (PLC) or by a computer fitted with a DeviceNet™ master card.

Technical specifications:

• Measuring range -55 °C … +125 °C;
• Temperature measurement error:
  
  • over the range 0 °C … +50 °C ± 0.2 °C;
  • over the range -10 °C … +85 °C ± 0.5 °C;
• Resolution of the measuring path — 0.0625 °C;
• Sensor powered from the DeviceNet™ network at 11…25 V;
• Number of sensors per line: no more than 62;
• Protection rating per ДСТУ ГОСТ 14255, EN 60529/IEC 529 — IP67;
• The sensor's wetted parts are made of food-grade stainless steel (12Х18Н10Т).
