Monnit_temp_sensor

industrial-temperaturesensor

The Monnit commercial sensors versions are provided with a coin cell which can last up to two years depending on usage. The industrial grade edition will last up to 10 years autonomy. Available in 868 Mhz (most GCC countries) and 433 Mhz (KSA) the sensors are sending values to the gateway at regular intervals (usually once every 15 minutes).

Industrial temperature sensor

industrial-temperaturesensorGeneral Description

Monnit’s industrial wireless temperature sensor uses a thermistor to accurately measure temperatures from -40°C to 85°C. Perfect for measuring ambient conditions in temperature critical applications such as facilities or server rooms.

Features

• Accurate to +/- 1 °C

• Increased accuracy by user calibration to +/- 0.25 °C  

Principle of Operation

The Monnit industrial wireless temperature sensor outputs the ambient temperature in degrees Celsius. It is programmed to sleep for a user-specified time interval (heartbeat) and then wakeup, send power to the NTC Thermistor, wait for the reading to stabilize, calculate the temperature and transmit the information to the wireless gateway (CloudGate).

To stay within the abilities of the processor, the temperature is computed from a data table provided by the manufacturer. To reduce error, a variable resistor configuration is implemented over specified temperature ranges.

Industrial Dry Contact sensor

General Description

Monnit_industrial-dry-contactMonnit’s industrial wireless dry contact sensor can be used to detect contact between two wired contact points. This sensor can be used with an external mechanical switch or a contact plate.

Features

– 30 cm lead wires.
– can integrate with switches

Principle of Operation

The Monnit industrial wireless dry contact sensor detects when their is contact between the two wired end points. It can easily be integrated into existing switches or contact plates. When the sensor detects contact between the two end points, it will immediately turn on the RF radio and transmit the data to the wireless gateway (CloudGate with Monnit receiver board). The sensor can be configured to detect both closed and open loops alerting if contact is made or broken.

Industrial Pulse Input

Monnit_industrial-pulse-counterGeneral Description

Monnit’s industrial wireless pulse counter can be connected to the pulse output of a system (water meter, power meter, etc.) to count the number of actuations within a given time frame.

Features

• Counts the number of pulses in given time frame, or aggregates pulses in an ongoing accumulation.

• 3 filter settings: No filter, 4 Hz filter, and 40 Hz filter.

• Capable of counting passive (open/closed switch) and active (Up to +15 VDC) pulses.

• Capable of counting the positive edge, negative edge, or both edges of a pulse. 

Principle of Operation

The Monnit wireless filtered pulse counter is an electronic counter capable of counting passive (open/closed switch) or active (Up to +15 VDC) pulses. The counter includes 3 software configurable low pass filter settings (No filter, 40 Hz filter, or 4 Hz filter). The pulse counter filters pulses with pulse widths greater than those designated in the technical specifcations. For example, if the 4Hz filter is set, the pulse counter will count a pulse if the pulse width is longer than 250 ms, if the pulse width is shorter than 250 ms it will be completely or partially filtered (See the Technical Specification table for detailed filtering information).

  • Dimensions: 58.8mm x 35mm x 94mm
  • Antenna: 3dBi RP SMA antenna
  • Operating Temperature: -7° to +60°C
  • Transmission Range: 100-150 m. non-line-of-sight*
  • Battery life: programmable from the CloudGate gateway: at 1 hour heartbeat setting, battery will last ~ 4-5 years.**

Industrial 0-20mA Analog Input

Monnit_industrial-0-1maGeneral Description

Monnit’s industrial wireless 0-20mA current meter is capable of measuring the current off another device or sensor, up to 20mA (DC), by connecting the leads on the sensor to the positive and ground terminals of the device being measured.

Features

• Measures one 0-20mA current input 

Principle of Operation

By connecting the leads on the Monnit industrial wireless 0-20 mA current meter to the positive and ground terminals of another device, the sensor can measure the current and send data to the CloudGate gateway. The data is stored in the concentrator system and can be reviewed and exported as a database (with time stamp) or graph. Notifications can be set up through the CloudGate to alert the user when certain thresholds have been met or exceeded.
