Choosing a model
DT300 or DT310
The DHMSCare DT300 measures vibration from 0–1000 Hz, for everyday motors, pumps and fans, while the DT310 measures 0–6000 Hz with detailed waveforms to catch gear and bearing wear early. Choose the DT310 for gearboxes and machines where early bearing wear matters most.
DT310 or DT311
The DHMSCare DT311 measures exactly what the DT310 measures, and adds an external antenna for machines inside enclosed metal structures. Choose the DT310 for open machines and the DT311 when the machine sits inside a metal guard or housing.
Metal enclosures and steel structures
Yes, with the right model: the DHMSCare DT311 has an external antenna for machines inside metal enclosures, and the DR100 repeater fills signal dead zones. Plants with heavy steel structures often use both.
Speed and start/stop sensors
Choose a DHMSCare DT320, DT321, DT400 or DT420 when you need rotating speed and start/stop detection as well as vibration and temperature. The DT320 and DT321 add edge AI, analysis done inside the sensor itself, to the DT310 and DT311. The DT400 and DT420 measure up to ±60 g from 0–8000 Hz for machines that run at changing speeds or stop and start often.
Specification notes
Frequency response
The DT300 and DT301 cover 0–1000 Hz; the DT310, DT311, DT320 and DT321 cover 0–6000 Hz (±3 dB); the DT400 and DT420 cover 0–8000 Hz (±3 dB). Frequency response is the range of vibration frequencies a sensor can measure, and a wider range shows bearing and gear faults earlier.
Sampling and waveform points
The DT310, DT311, DT320, DT321, DT400 and DT420 record detailed vibration waveforms, and the sampling rate and waveform length of each model are in the full spec sheet, sent on request from the product page. More waveform points give a sharper picture of each vibration frequency, and the DT310 to DT321 also have a high-resolution mode that reads one axis at a time.
How often it measures
The collection interval is configurable per machine and monitoring need; default values are in the full datasheet, available on request from the product page.
Ingress rating
Every DHMSCare DT sensor is rated IP69, built for high-pressure, high-temperature washdown. IP69 is the highest rating for protection against dust and water jets; the gateways and the DR100 repeater are rated IP65 for normal plant conditions.
Surface temperature
DHMSCare DT sensors work on machine surfaces from −40 to 100 °C, in air temperatures from −40 to 80 °C, or −40 to 85 °C for the DT400 and DT420. For hotter surfaces, such as kiln shells or dryers, ask us before you install.
Hazardous areas
Yes. DHMSCare offers hardware certified under IECEx, the international scheme for equipment used in explosive atmospheres; the certificate states which models and zones it covers. Ask us for the certificate before you order for a hazardous area.
Certifications
DHMSCare DT sensors carry CE marking, the DMG310 gateway carries CE, FCC and IMDA (Singapore), and the DMG311 gateway carries CE and FCC. CE covers sale in Europe, FCC in the United States, and IMDA in Singapore; for hazardous areas, see the IECEx paragraph above.
Mounting
DHMSCare sensors are bonded with industrial adhesive near the bearing seat, with no machine modification, and each one is bound to its measuring point with a tap of the phone. A mounting block is available where the surface is not suitable for direct bonding.
Sensors per machine
DHMSCare plans start from one sensor per machine, placed near the bearing seat, and you add sensors where a machine has more measuring points, such as a motor that drives a gearbox. Each industry page lists the measuring points per machine.
Battery life
The DT300–DT321 sensors are rated for 5 years after activation; the DT400 and DT420 are rated for 3 years after activation. Battery life counts from the day a sensor is activated, not from the day it is delivered.
Replacing the battery
Today only the DHMSCare DT400 has a replaceable battery; the other models do not.
Ultrasound, current and flux
No. DHMSCare wireless sensors measure vibration and temperature, and the DT320, DT321, DT400 and DT420 also measure rotating speed. They do not capture ultrasound, motor current or magnetic flux.
Gateway notes
Wireless technology
DHMSCare sensors send their data to the gateway over industrial-grade Bluetooth 5.0 Class 1, a low-power radio standard, in the 2.4 GHz band. The gateway then uplinks to the platform over Ethernet or Wi-Fi on the DMG310, or Ethernet or 4G on the DMG311.
Distance to the gateway
About 300 m in open, line-of-sight conditions, and typically 60–80 m inside a plant, depending on the layout and what stands between the sensor and the gateway. DHMSCare sensors use industrial-grade Bluetooth 5.0 Class 1, not consumer-grade Bluetooth. Where the signal is weak, a DR100 repeater passes it on.
Repeater
Yes. The DHMSCare DR100 wireless repeater extends the signal between sensors and the gateway, covers dead zones and carries up to 20 sensors at about 50 m in an industrial environment. It runs on mains power or on its own battery for about 6 months.
Reliability for critical machines
Yes, for condition monitoring: DHMSCare sensors report at set intervals over industrial-grade Bluetooth 5.0 Class 1, typically 60–80 m from the gateway inside a plant, and the gateway stores readings during a network outage. The platform shows when any sensor or gateway goes offline. For protection that must stop a machine within milliseconds, keep a wired protection system; DHMSCare monitors, it does not trip machines.
Network outage
No data is lost in a short outage: the DHMSCare gateway stores readings while the network is down and uploads them when the connection returns.
4G gateway
Yes. The DHMSCare DMG311 gateway connects over 4G or Ethernet, so sites without plant Wi-Fi or network access can still send sensor data to the platform. It takes a standard Nano-SIM card.
Radio approval by country
DHMSCare gateways carry CE and FCC approval, and the DMG310 also carries IMDA approval for Singapore. For another country, such as Indonesia, ask us to confirm the approval before you order.
Without plant Wi-Fi or IT
No. The DHMSCare DMG311 gateway connects over 4G, so DHMSCare can run without your plant Wi-Fi or IT network. The DMG310 uses plant Ethernet or Wi-Fi where you prefer that.
