Measuring relays for monitoring physical values

Measuring relays for monitoring physical values

Safely monitor speed, temperature or fill level

For the monitoring of physical variables such as speed, temperature or fill level, DOLD features speed and/or standstill monitors, temperature monitors and thermistor motor protection relays as well as level relays especially for you. The DOLD measuring relays offer you advantages such as a safe monitoring of standstills in machine with rotating parts as well as a reliable monitoring of the motor condition during increasing temperatures. In the area of fill level measuring, a high measuring range allows liquid and foam to be distinguished between.
