The wireless pressure transmitter has optimized the circuit design, power management, communication protocol, and realized the “micro-power consumption” design of wireless communication. Using micro-transmission power and high-sensitivity receiving strategy, it has the advantages of real-time online monitoring of battery power and so on.

The wireless pressure transmitter system is mainly composed of pressure sensor, signal processing circuit, wireless module, power management circuit, battery and antenna. On this basis, a wireless remote transmission module is added, which can form a pressure acquisition system with our intelligent wireless receiving terminal.

This system has changed the transmission mode of RS485 and 4-20mA current signal and the power supply mode of switching power supply in the past, and used 3.6V lithium battery for power supply. This simplifies the installation method and saves the cost of customer wiring. Really achieve the purpose of energy saving and environmental protection.

The wireless pressure transmitter is a high-precision, low-power radio transmission pressure detection instrument. Powered by lithium battery, IP65 waterproof cast aluminum casing. Support data recording and data supplementary transmission functions. No wiring, no external power supply required. Built-in 3.6V lithium battery.

In the field of the Internet of Things, there are various communication technologies at the same time.

Divided by the dimension of transmission distance, in the field of local area wireless network, there are BLE, Wi-Fi, ZigBee, etc., which are widely used in home, enterprise and other scenarios.

For wide-area wireless networks, there are LoRa, NB-IoT, etc., which are specially used for low-rate, low-power, and wide-coverage IoT services.

NB-IOT/Zigbee/Lora comparison

WiFi is ubiquitous in life, but we know very little about NB-IOT, Zigbee, and Lora. Sino-Inst compares the three wireless networking solutions from five aspects to help you understand these three technologies.

  1. Transmission distance comparison

NB-IoT: Long-distance, up to ten kilometers, generally more than 10KM; NB-IoT technology improves the power spectral density, realizes wide-area coverage, and effectively solves the problem that existing wireless signals are difficult to cover.

LoRa: Long distance, up to ten kilometers, 1~2 kilometers in cities, and 20 kilometers in suburbs;

ZigBee: short distance, 10 meters to 100 meters level;

  1. Single-network access node capacity

NB-IOT: about 200,000. Compared with traditional 2G, 3G and 4G, NB-IoT has a 50-100 times increase in uplink capacity;

LoRa: about 60,000, which is actually related to the number of gateway channels, node packet sending frequency, data packet size, etc. Generally, there are 500 to 5000;

ZigBee: more than 60,000 in theory, 200-500 in general

  1. Battery life

NB-IOT: theoretical about 10 years / AA battery, no need to charge;

LoRa: Theoretically about 10 years/AA battery;

ZigBee: Theoretically about 2 years/AA battery;

  1. Cost

NB-IOT: The cost of the module is less than 5 US dollars, and the future target is reduced to 1 US dollar. The low cost and low power consumption make NB-IOT more cost-effective and wider application range than other types of IoT;

LoRa: The module is about $5;

ZigBee: The module is about 1~2 US dollars;

  1. Transmission speed

NB-IOT: theoretical 160kbp ~ 250Kbps, generally less than 100kbps in practice, limited by low-speed communication interface UART;

LoRa: 0.3~50kbps;

ZigBee: theoretical 250kps, practically less than 100kbps, limited low-speed communication interface UART;

Wireless Pressure Transducer Price

Wireless Pressure Transducer Price will cost more than ordinary pressure transmitters.

First of all, the parameters that must be seen when purchasing a pressure transmitter are:
Pressure range. Range. Measurement medium. Installation method-threaded flange clamps, etc. Installation dimensions. Temperature. Whether with display. Whether with HART protocol. Output type. Current output or voltage output. Explosion-proof level, protection level. Accessories. Mounting bracket.

The above parameters will affect the price of the pressure transmitter.
Sino-Inst, as the manufacturer of wireless pressure transmitter, offer you with the best price.


Wireless pressure sensors are also wireless pressure transmitters.

The wireless pressure transmitter is added with a wireless remote transmission module, which can form a pressure acquisition system with an intelligent wireless receiving terminal. Including GPRS/LoRa/NB-IoT/ZigBee multiple transmission methods are optional.

Pressure transmitters can be categorized into four main types:

  • Gauge Pressure Transmitter.
  • Absolute Transmitters.
  • Differential-Pressure Transmitter.
  • Multivariable Pressure Transmitters.

Extended Reading: Liquid pressure sensor

A pressure transmitter is a device that converts pressure into pneumatic or electric signals for control and remote transmission.

It can convert physical pressure parameters such as gas and liquid sensed by the load cell sensor into standard electrical signals (such as 4~20mADC, etc.). Measurement, indication and process adjustment are carried out by supplying secondary instruments such as indicating alarms, recorders and regulators.
