OVERVIEW The Casella 120 Acoustic Calibrator is the smallest of its type in the world; with a rugged, over-moulded design for use in field environments. The field calibration of Sound Level Meters is an essential procedure when carrying out any type of noise survey both before and after each measurement sequence. This ensures that instruments are providing consistently accurate readings necessary for monitoring to ensure compliance with workplace and environmental noise regulations. The 120 is therefore designed and manufactured to comply with the requirements of IEC 60942: 2003 and ANSI S1.40: 2006. These standards stipulate accurate calibration over a wide range of temperature, humidity and pressure conditions, typical of field work, ensuring accurate calibration in all conditions. The Casella 120 Acoustic Calibrator callibrate the 24x Series Sound Level Meter. DIGITAL TECHNOLOGY FOR OPTIMUM ACCURACY The 120 is compact and ergonomically designed with simplicity and ease of use being the highest priorities. Key features include a simple keypad for intuitive control, permitting calibration level changes when required. When used with instruments like the-62X series, calibration routines commence automatically as soon as a calibration tone is detected to further simplify the task. The 120 uses a MEMS microphone and a digital feedback loop to maintain the acoustic pressure in the cavity at the required level. An indicator shows if the sound level meter microphone is incorrectly inserted into the cavity, removing any potential for calibration error. The microprocessor control detects when the microphone is removed and automatically switches off the calibration tone. This conserves battery power, allowing batteries to last for up to 2 years of operation. Both the CEL-120/1 and CEL-120/2 calibrator accept all industry standard 1/2“ microphone capsules. Smaller 1/4“ microphones may be accommodated using the 1/2“ to 1/4“ adaptor (CEL-4726). The relevant 120 also comes as standard with our range of noise monitoring kits.

  • Parameters

Portable Vibration Calibrator: SV 111 is a multi-frequency vibration calibrator designed for in-situ checks according to ISO 8041. The SV 111 is suitable for calibration checks of various types of vibration meters at different frequencies from 16 Hz up to 640 Hz. Depending on the selected frequency user may select level of calibration from 1 m/s2 to 10 m/s2. Shaker can be loaded with large weight up to 1 kilogram at 16 Hz. The design of the calibrator is based on the built-in triaxial reference accelerometer and microprocessor-controlled shaker. Following ISO 8041 requirement the reference accelerometer measures the cross-axis / transverse vibrations to detect interference on the calibration signal. Faults caused by transverse vibrations are indicated by three LEDS on the calibrator’s panel. This unique solution ensures the excellent stability of the calibration level & frequency independently from mass of the testing object. For calibration checks of tri-axial sensors set of dedicated adapters is available including a special adapter to Svantek whole-body sensors (seat-pads) for direct mounting on the shaker. Other types of vibration transducers can be conveniently attached using mounting stud, mounting disc or dedicated adapter.
