MEASURING TRANSMITTERS
Measuring transmitters convert electrical and non-electrical quantities (e.g. temperature – input are temperature sensors or different current and voltage signals) into standard voltage and current signals. We distinguish them either by their housing (independent housing or built in housing, e.g. mounting inside the temperature sensor head) or their concept (with galvanic isolation of input/output/power or without galvanic isolation).
Measuring transmitters of the MPx 3xx family are installed on a DIN rail in the el. cabinet. The electronics are constructed inside a 22mm wide ABS housing.
Input: temperature sensor PT 100 (three wire ), DC voltage or DC current. Output: DC voltage (0-5V, 1-5V, 0-10V, 2-10V, power 24VDC).
Temperature measurements in automation systems
Input: temperature sensor PT 100 or PT 1000 (three wire), DC voltage, DC current. Output: current 4-20mA, power 24VDC (current loop).

DATA LOGGERS
The GSR and PSR data logger families measure and register different quantities such as pressure, level, flow, temperature… Power supply is adapted to the application site. It can be grid, battery or solar powered. According to their construction we distinguish compact loggers and loggers with dislocated electronics. Data transfer may be local, networked or wireless.
The GSR 120 data logger family consists of two devices:
They are characterized by a compact stainless steel immersion housing, battery or external power supply, communication connection RS 485 and the possibility of connecting a GSM modem for wireless data transmission.

The GSR 130 logger family ist similar to GSR 120, but the GSR 130 logger measures and registers absolute level (pressure) and therefore needs no vented connection cable. The Data logger GSR 130 NT measures and registers level (pressure) and temperature, the GSR 130 NTG measures and registers level, temperature and also conductivity of the media (water).
The data logger is descended with an ordinary cable-rope at a suitable place in a well and fixed at the top. The data logger has to be taken out of the water for data transmission.
