4) explosion-proof marks: Ex ib II C T4 Gb, explosion-proof certificate: CE18.2230 X;
5) power supply: lithium thionyl chloride batteries ER34615 type (executive standard: SJ52278/1), two primary battery in parallel, 3.6 V 38 ah capacity; Battery connector SM - 2 p (female head: 1 foot the anode, cathode) 2 feet connected to the instrument; Scope of supply voltage, 3.0 V ~ 3.6 VDC;
6) battery work time: 1 year or more (pressure acquisition frequency 1 times/min, communication frequency 1 times/h);
7) replace the battery: open the rear cover, through standard SM - 2 p interface quick replacement;
8) long-term stability, drift, plus or minus 0.1% FS/year;
9) measuring performance: range, 0 ~ 2.5 MPa, 0 ~ 6.0 MPa, 0 ~ 25 MPa, 0 ~ 40 MPa, 0 ~ 60 MPa,; F.S precision, 0.5%; Can be made according to the actual demand; In line with the GB/T 28474.1, GB/T 28474.2 rules;
10) pressure sensor: the piezoresistive type core body, pressure overload capacity, 150% FS.
11) process connection interface: M20X1. 5 1/2 "NPT, or can be made according to the actual demand;
12) communication: 4 g (full netcom, compatible with 3 g / 2 g);
13) communication protocol: follow the temperature, pressure transmitter, a cellular network connection protocol, realize oilfield DMZ server access;
14) online debugging and setting function: possess online without unloading installation, by means of the instrument panel or configure a serial port and computer for instrument for debugging, and set up; Set the data content includes:
Ø telecommunication working parameters: the server IP address and port number;
Ø measurement parameters: the alarm can make, upper and lower limit, time delay and dead zone, maximum range, minimum, decimal digits, upload alarm frequency, sampling frequency and variation;
Instrument, when the power setting data keep;
Front panel LED: there are two colors red and green, red represents pressure collection status and sleep to wake up, the green LED on behalf of built chain for NB - IOT network state
Front panel reset: by magnet, right in front of the shell cover, the magnet to reset up the arrow and remove the magnet stability for 3 to 5 seconds, LED red light flashes three times, liquid crystal display 8888 synchronous flash three times, also on behalf of the instrument reset successfully, the main purpose of the reset it is changed into the instrument internal parameters, or refresh the pressure value, and build up a network link to refresh.
Instrument to open the back cover, back cover internal batteries, button, switch, USB debug port, function is introduced as follows:
Rear panel K1: because there are a long cycle, instrument reporting period in the process of debugging, can press K1 key, meter initiative to establish a network link, a group to report the current pressure data. If K1 is mainly used for debugging network normal use.
Rear panel K2: as the instrument to cycle is long cycle, see some application field need to implement the pressure of every number, in the process of debugging, can press K2 keys, instrument active continuous acquisition current pressure 300 seconds, LCD real-time refresh, this function is only site acquisition does not upload. K2 is mainly used for the pressure adjustment.
Rear panel switch: switch points 3, three gear switch, intermediate gear closed, and is open.
Rear panel USB: USB + debug software, can easily enter the IP address, network number, such as debugging parameter, see debugging software manual.
Rear panel battery replacement: first, will the power switch is closed, will be around two M3 knurled screw, wrung out by hand, then take out K1 and K2 circuit board cover vertical black plug disconnect battery SM, replace the new battery, reinsert the SM plug, then insert K1 and K2 circuit board on the needle gently vertically inserted, the last two M3 knurled screw manually turned it on, turn on the switch, the whole process of operation, the need to pay attention to, K1 and K2 circuit board gently pull plug. Finally, please tighten the back cover. Real photo as follows:

On-site installation instructions
5.1. All transmitter through digital calibration, the different between the transmitter has the complete consistency and interchangeability;
5.2. In transit, all of the transmitter battery is in the off state, pressure transmitter installation on site, need to unscrew header back cover, open the battery switch, attention should be paid to tighten sheath, prevent leaking;
5.3. Pipeline and often stop well installed wireless cellular network pressure transmitter, pressure transmitter will be ready to install on the pipe first valve type needle valve or gate valve closed, and then there are two installation method: (1) the pressure transmitter directly screwing in type needle valve port; (2) will live or port adapter type screwing in the needle valve, then transfer transmitter screwing in live or joint on port, this kind of installation method to increase the living or connector to adjust the direction. Type installed, open the needle valve valve to confirm no leakage phenomenon, namely the installation qualification;
5.4. The cellular network wireless pressure transmitter after the installation is complete, can through the keys or debugging tools for network parameter Settings.
5.5. Transducer without using for a long time, can through the debugging tools set pressure transmitter to sleep patterns, (transmitter in the process of the factory warehouse, unified set to sleep mode or closed, the need to adjust and activation can be normal use). Debugging software interface online list below:
6. Matters needing attention
6.1. This product is the battery model used for ER34615M - 3.6 V38Ah; It is prohibited to use other model battery.
6.2. Product antenna casing for the plastic material, potentially dangerous electrostatic charge! Use should be avoided in the friction! Please use wet cloth to wipe clean!
