Buy Temtop Auxiliary PM sensors here

In air quality monitoring, the sensor is not just another component inside the system. It decides whether the data is useful, repeatable, and suitable for actual field decisions.

A buyer may ask for a “PM sensor,” but the real requirement can be very different. One application may need PM1.0, PM2.5, PM10 and TSP mass concentration for a dust monitoring station. Another may need particle counting by size channel for filter testing. A third may need a compact PM sensor module that can be integrated into an OEM monitoring device with an external pump.

That is where Temtop auxiliary PM sensors such as PMS 10, PMS 11 and PMS 16 become useful. These models are designed for online atmospheric and air monitoring applications, but each model fits a different type of system requirement. The PMS 10 is a pump-suction laser dust monitor for PM concentration monitoring, PMS 11 is an embedded particle counter, and PMS 16 is an external pump laser PM sensor.

This guide explains how to select the right Temtop auxiliary PM sensor for industrial dust monitoring, air quality systems, filter testing, oil-smoke monitoring, and OEM integration.

What Are Auxiliary PM Sensors?

Auxiliary PM sensors are particle measurement modules used inside a larger air quality monitoring system. They are generally not purchased as handheld consumer monitors. Instead, they are selected by OEMs, system integrators, environmental monitoring companies, and instrumentation teams who want to build or upgrade a monitoring device.

These sensors help measure airborne particles such as PM1.0, PM2.5, PM10, TSP, or particle counts in different size channels. In real applications, this data may be used for:

• Dust monitoring
• Ambient air quality monitoring
• Micro air monitoring stations
• Filter testing
• Oil-smoke monitoring
• Industrial ventilation monitoring
• OEM air quality equipment
• Environmental data acquisition systems

The main selection point is not only “which sensor is available?” The better question is:

Do you need PM mass concentration, particle counting, built-in pump sampling, external pump flexibility, RS485 communication, or compact embedded integration?

How Temtop PMS Sensors Work

Temtop PMS sensors use the Mie scattering principle. In simple terms, air passes through a light collection chamber, particles scatter the laser beam, and the internal photoelectric system converts scattered light into electrical pulses. The number of pulses helps identify the number of particles, while the pulse amplitude relates to particle size.

For buyers, the important point is this:

Laser particle sensing is useful when you need continuous particle-related data in an online monitoring system, but installation, airflow, humidity, calibration, and communication compatibility must be handled correctly.

A good PM sensor can still give poor results if the airflow path is wrong, the sampling tube is too long, humidity is not managed, or the control system cannot read the sensor output properly.

Common Selection Mistakes to Avoid

1. Choosing a PM sensor without deciding between mass concentration and particle count

PM2.5/PM10 concentration and particle count by size channel are not the same requirement. PMS 10 and PMS 16 are better for PM mass concentration, while PMS 11 is better for particle counting.

2. Ignoring the pump arrangement

PMS 10 has built-in pump suction. PMS 16 uses an external pump arrangement. This affects enclosure design, sampling stability and installation complexity.

3. Ignoring communication compatibility

Check whether your system needs RS485, Modbus RTU or TTL-level communication before selection.

4. Not checking power supply

PMS 10 and PMS 11 use 12 VDC, while PMS 16 uses 5 VDC. This matters during panel design or OEM PCB integration.

5. Poor sampling tube design

Long or poorly designed sampling tubes can affect reading accuracy. For enclosure installation, the hose length should be controlled within 30 cm as specified in the manuals.

6. Ignoring humidity effect

High humidity can affect particle measurement correlation. For demanding applications, confirm whether drying, heating or humidity compensation is needed.

7. Selecting only by price

The wrong PM sensor can create integration issues, unstable data or poor sampling accuracy. Selection should be based on measurement type, airflow, communication, power supply and installation design.

FAQs

1. Which Temtop PMS sensor is best for PM2.5 and PM10 monitoring?

For PM2.5 and PM10 mass concentration monitoring, PMS 10 and PMS 16 are more suitable options. PMS 10 is better when built-in pump suction and RS485 integration are required. PMS 16 is better for compact embedded systems with external pump design.

2. Which model should I use for particle counting?

Use Temtop PMS 11 when the requirement is particle counting by size channel such as 0.3 µm, 0.5 µm, 0.7 µm, 1.0 µm, 2.5 µm and 5.0 µm.

3. What is the main difference between PMS 10 and PMS 16?

PMS 10 is a pump-suction laser dust monitor with 12 VDC power and RS485 communication. PMS 16 is a compact external pump laser PM sensor with 5 VDC power and TTL / Modbus RTU communication.

4. Can these sensors be used in outdoor monitoring systems?

They can be used in outdoor fixed equipment only when the system designer provides proper protection against rain, snow, sandstorm, dust, catkins and other environmental factors. The sensor or monitor itself should be integrated into a suitable enclosure and sampling design.

5. Why is sampling tube length important?

If the sensor is mounted inside an enclosure, the air inlet must be connected properly to an external probe. Temtop recommends controlling the connecting hose length within 30 cm to obtain accurate sampling results.
