Temperature Monitoring and Acquisition Products

Providing unmatched products for testing, product development, process monitoring, OEM product integration

Dust-Tight & Waterproof


Temperature monitoring and acquisition devices with serial data output options are available as circuit board assemblies and with enclosures. Enclosed products provide dust-tight, waterproof IP66 rating with three cable glands. Inside enclosures ample space for cable connections are provided. Transparent enclosure covers provide visual for operational LEDs, switch position and the wire connections. Pre-programmed for a thermistor with many mounting options that meets most applications needs. User programmable thermistor sensor capability provides additional flexibility to meet every application needs.

Wide Range & Accuracy


Temperature monitoring and acquisition devices with 4 sensor channels implement advance proprietary temperature mapping and noise reduction techniques that can be used in any application that requires temperature monitoring, acquisition, and control. Measurement range is -50C to +150C with fast and slow data output options.

Versatile

  • No calibration required with default sensor in addition to programmability

  • Wide input voltage: 6.7- 36VDC, 5VDC

  • RS485 networked or one-to-one data output

  • 3.3V or 5V CMOS Logic (UART) networked or one-to-one data output (for embedded systems)

  • 30kV ESD protected I/Os

  • Current limited outputs

  • Overvoltage protected inputs

  • Reverse polarity protection for power inputs

  • 4 temperature sensor channels used with many robust thermistor probe options from Littlefuse

  • -40C to +125C measurement range with less than 1C error

Data Output Types

  • 3 data output options: Modbus RTU compatible protocol, ASCII data stream and binary data stream

  • Command-response communication in a network or one-to-one

  • 254 addressable devices, up to 128 devices in one RS485 network

  • Time stamping with slow binary data stream

  • ASCII data stream in tab delimited format

  • Binary data stream used for compact data with CRC error detection 

  • Fast data stream in ASCII and binary formats: 25ms to 100ms

  • Slow data stream in ASCII and binary formats

Advanced Features

  • Programmable with thermistor sensor – simple three point programming without loss of specified accuracy, no look-up table

  • Programmable power dissipation coefficients (PDCs) – depending on thermistor used provides flexibility to further improve accuracy

  • Programmable slow data stream period 1 to 254 seconds

  • Sensor status detection – sensor status on an active channel is detected as connected, open or short

  • Active channel adjustment: during power up if a sensor is not detected on a channel that channel is removed from the data stream

  • Time elapsed/stamp with slow binary data stream and protocol

  • Min/max temperature recording and reset with protocol
