GPRS, ZigBee, NB-IoT, LORA WIFI output Wireless pressure transmitter
Description
The model PT124B-289 is a low-power consumption wireless transmission digital pressure transmitter , it is battery power supply , and has 4 types of wireless transmission mode, including GPRS, LoRa ,ZigBee , NB-IoT .it adopt explosion-proof cast aluminum shall and SS304 joint, built-in high precision diffused silicon sensor chip & LCD screen, it can measure the gas, liquid, oil and other medium non-corrosion, with strong medium compatibility characteristics.
This series of products has many auxiliary functions such as zero clear, backlighting, on/off, unit switching, low voltage alarm, sample rate settable, frequency settable, high and low voltage alarm value settable, instant pressure alarm, etc.
The GPRS wireless pressure transmitter rely on China Mobile's mature GPRS network, upload the field pipeline pressure to the cloud. Users can match IP address and other conventional parameters on-site or remotely.
The LoRa wireless pressure transmitter, which is used with LoRa gateway, has the advantages of low power consumption, short transmission distance, strong signal penetration and self organizing network.
The ZigBee wireless pressure transmitter , which is short transmitter distance, low complexity, low power consumption, low speed, low cost two-way wireless communication technology
The NB-IoT wireless pressure transmitter adopts the latest NB-IoT technology, long transmission distance , with the advantages of low power consumption, high transmission efficiency and low cost.
