Description
1. Description
The NetTemp16 system has two channels and each one can connect at most 8 pieces of TEMP75 sensors, and the length of the cable can most extend to 300 meter. The maximum length depends on the disturb of the delectromaqnetism in the environment. This system can be used to measure multi-point temperature in storage, refriqeratory storage, office and so on. It is controled by a computer to count and manage the data. The software can automately accomplish counting the data and create the curve , save the data to files, analyse the mix,min and the average of the records and so on.
2. Function & Feature
a) Range of measuring: -40~+120 C; -40~+248F;
b) Resolution rate: 0.06C
c) Precision:< 1.5C;
d) Collecting speed:500m/s
e) Electricity:< 10 mA; Voltage: 3~6V
3. Function & Operating Instruction
a. Componients connecting and extending
NetTemp16 has two normative audio-sockets of 3.5mm dia. , channel A and channel B. Each channel connects with the sensors by a bus , which is make up of three signal cables, and each channel can connect at most 8 sensors. That is to say a NetTemp16 device can make up a net of 16 points at most..
If your system need to measure more than 16 points as a large warehouse, you can connect more NetTemp devices to the computer . If there is not enough USB port you can use the USB HUB to enlarge it. See the picture showing below.
The longest length of the cables of each channel can be 300 meters. The largest distance depends on the quality of the cables, the molestation of electromaqnetism in the environment and other factors. And if the records is tally with the validatory temperature, you can continue to extend the length of the cable.
We suggest you to use the screen cables to make up the net, and the diameter of the cable should be wide as possible, that the signal can be more steady.
b. Special sensor of the net temperature testing
The number of the sensor can’t be same in the same channel of the net, or the system will failure to identify them. The number of the sensor is assent to be T0,T1,T2,T3,T4,T5,T6,T7. When the system identifies the sensors connected in the channel, it will show the numbers of them automately. Then the user can easily identify the number and the point.
The standard length of the cable of the Tx (from T0 to T7) is 1~5 meters. And if you need a special length you can book it from us. The shell of the sensors is protected from water and can be put into water or a wet environment. But note that if put it in a caustic environment, the metal shell may be cankered. You can brush some antirust on the face of it or do something else to protect it from canker.
