BJ-W3000 Wireless Temperature Monitor

BJ-W3000 Wireless Temperature monitor

The BJ-W3000 Wireless Temperature monitor is a device that
measures and transmits temperature and humidity data via wireless
technology. It offers economic and flexible systems for every
temperature and humidity measurement requirement. The wireless
sensing units can be installed anywhere within radius from the
local base receiver unit. The device is particularly useful in the
pharmaceutical industry, laboratories, the food industry, cold
storage and warehousing, transport, building management,
environmental monitoring, horticulture, and animal husbandry.

Technical Parameters

The device has the following technical parameters:

Low-size (144 x 144 mm), panel-mounting base unit
Instantaneous, maximum and minimum values of each measured
parameter
Alarm output (indication through a lighting led)
RS-485 or Ethernet communication to a pc (optional)
Multiple data receivers can monitor temperature
Receive the data form wireless sensing unit
Pre-defined high or low temperature conditions
Transmits the data wirelessly to local receiver

Installation and Start-up

Before using the BJ-W3000 Wireless Temperature monitor, please
read the user manual carefully and follow the instructions
below:

Make sure that the power supply is within the provisions of the
instrument before turning on the power supply.
When installing, the current input terminal must not be open,
and voltage input terminals must not be short-circuited.
Communication terminal (RS485) is strictly prohibited to impose
high pressure.
Ensure that the instrument wiring is consistent with the
internal system settings.
When communicating with the PC, instrument communication
parameters must be consistent with the PC.

In case of over-temperature or under-temperature conditions, the
alarm sounds with a warning light indicator to notify you of the
abnormal condition. Adding on additional sensing units is easy; use
multiple receivers, the units work together to keep you on top of
the environmental conditions within your space.
