Thermal sensor for indoor usage at RS-485 bus (communication over long distances) with a simple communication protocol. The sensor can be used separately but is designed for connection to the Poseidon measuring unit and transmit temperature over SNMP, WEB or XML.
Temp-485 is a thermal sensor communicating over RS-485 bus. The sensor is designed for vertical indoor mounting to walls.
The measured temperature is sent directly in °C by a simple text protocol. Up to 26 sensors of this type can be connected to a single 4-conductor busbar. The busbar uses 4 wires, two with a standard RS-485 line, the other two are used for sensors' power supply. RS-485 communication line works up to 1000m distance.
For temperature measuring the sensor uses semi-conductor element which measures with accuracy of ± 0,5°C. On the sensor there is LED that signalizes temperature measuring in progress by blinking.
Application
Extensive temperature measuring systems
Industrial measuring and regulation
Temperature measuring in grocery, pharmaceutical and other storage buildings
Temperature measuring in production and residential premises (option to connect long-distance sensors over RS-485)
After connection the Temp-485 probe to the Poseidon unit – temperature transmission over Ethernet or Internet
After connection to Poseidon model 2xxx – possible logging of up to 100 000 values into internal Flash memory
Basic Properites
Temperature measuring within the range of -10°C to +85°C
Communication and sensor state indication by LED
Easy wall mounting
Communication over the RS-485 line (up to 1 000 m distance)
Temperature in simple communication protocol, directly in centigrade degree. Poseidon can convert to Kelvin or Fahrenheit degree.
Minimal power consumption, possible power supply by unstabilized voltage
The sensor by itself can send a temperature value according to preset time interval, which can be from 1 to 5000 seconds (proximately 1 hour and 23 minutes)
The sensor address at RS-485 bus can also be set by jumpers inside the sensor
The sensor cooperates with SNMP thermometer Poseidon
Temperature transmitting over various protocols HTML, XML, WEB, SNMP)
Values log to PC or in Poseidon unit (2250 model)
Alarm for safe range exceeding (SNMP Trap, Email, SMS)
