The post HVAC40 – HVAC Transmitters and Hygrostats appeared first on Senseca.

]]> Over 40 years of experience in worldwide applications combined with a new design on accuracy, stability, simplicity and connectivity: this is the HVAC40 series. These transmitters and hygrostats measure temperature, relative humidity and dew point using an interchangeable relative humidity and temperature digital sensor.

The probe is available in three different versions:

  • fixed vertical probe for wall mounting
  • fixed probe with 2 m cable
  • fixed duct horizontal probe

Available outputs, depending on the model:

  • RS485 Modbus–RTU digital output
  • 0…10 V voltage analog output
  • 0…20 mA / 4…20 mA active current analog output
  • 2-wire (current loop) 4…20 mA analog output
  • ON/OFF relay switch

Relay versions with settable alarm thresholds, hysteresis and delay and supplied as standard with LCD display. Optional LCD for all other versions.

The instruments are factory calibrated and ready for use.

MKT - Mean Kinetic Temperature calculation. Optional with software according to FDA 21 CFR part 11.

The post HD208 – Compact Data Logger: Monitoring Temperature, RH and Dew Point appeared first on Senseca.

]]> The data loggers of the series HD208 are compact instruments for monitoring temperature, relative humidity (RH) and dew point temperature. Usable in a wide spectrum of applications, are available in various models (with or without LCD display):

• with 1 channel for temperature only
• with 1 channel for temperature and relative humidity

All models can be supplied with or without LCD display.

The logging function is extremely versatile; logging can be started and stopped manually, automatically or delayed.

For each quantity detected, two configurable alarm thresholds can alert the user if the measure exceeds the configured parameters.

The instrument automatically generates, after logging, a PDF report with charts of the variables collected and a CSV file with all measurements logged.

The basic application software HD35AP-S supplied with the instrument allows the configuration of the instrument, the real-time monitor of the measurements and the transfer of the acquired data into a database.

The HD35AP-CFR21 application software option allows the use of security features of the recorded data and configuration of the instrument in response to FDA 21 CFR part 11 recommendations.

The sensors are pre-calibrated and require no further calibration by the user. If necessary, the user can perform a new calibration using the HD35AP-S application software.
