Measurer room temperatures
Complex uses for the remote measurement temperatures. Transfer data is the speech link or constant telephone or the wire connection. Complex comprises from the measuring unit and receivers. Receiver has the display temperatures and alarm.
Characteristics:
 power supply: 220VAC / 5VA or 24VDC / 2VA
 temperature area: - outer sensor -30..90°C, the internal sensor on the device -10..50°C
 resolutions of showings: 0,1°C
 accuracy measurements: + / - 3°C (the defined accuracy LM335 of sensor)
 time refreshing of data: 5 second for the 2 channel, DTMF coding + the cheque sum
 alarm indication: for too low and too high temperature (the as regards voltage - sees herself the further text)
 appliance has is built in and alternatively the use of the measuring channel for transfer measured values of voltages 0..40V resolutions 0,01V also were able will use and for the supervision of states of accumulators 24VDC
 receiver display only one from the chosen measuring channel the alterable key SEL
 indication interrupts communications with the holding of the last correct accepted data (to switching off of power supplies)
 simple usage
 aluminic box
 quality bilding
 dimensions of transmitters: 104 * 220 * 56mm (l * w * h)
 dimension of double two channel receiver: 238 * 220 * 56 (l * w * h)
|
example of the double two channel version: left on right: transmitter for inner and outer temperature, transmitter for the inner temperature and voltage of accumulator also the double receiver who left shows the temperature of the measuring channel 1, and the right voltage of the measuring channel 2

example of showings of cause of alarms after pressing keys SET: measuring channel 1 has the too high temperature
|
Price double two channel versions: 7000 HRK (933Eur)
Possible version:
 the single receiver (for 2 measuring channel)
 activated the relay output in the event of the alarm state
 the measuring transmitter with the display temperatures / the voltage
 transfer of the different measuring analogic data pure 12 bitne resolutions (noise + / - 0,25 bit) - the all what that reduces to 0..4V in the resolution 1mV.
 one channel transfer with the refreshing of the every 2,5 the second
 different voltage power supplies
 etc.
