- Abstract:
- This paper presents a new temperature chamber in combination with the 2-MNdeadweight force standard machine (FSM) which allows testing and certification of load cells with nominal loads up to 2 MN (200 t) by the Physikalisch-Technische Bundesanstalt (PTB). This facility is unique in Europe; for the first time it offers manufacturers and customers the possibility to certify load cells with very high nominal loads as used in the heavy industry for instance.
In spite of a small installation space for the temperature chamber which is limited by the construction of the FSM the temperature chamber permits measurements in a temperature range from -20°C to +55°C combined with small spatial and temporal temperature gradients of < 0.2 K per 100 mm and per hour. Thus it fulfils entirely the requirements for testing load cells as defined in the OIML-Recommendation R60. - Keywords:
