System maintenance - Import export

Typically, the ASCO CO2 Gas Dosing System is used together with water desalination plants. The system is equipped with a CO2 pressure reducing valve, filtration unit, CO2 gas flowmeter, CO2 regulating valve, pressure gauges, safety valves and a completely prewired control cabinet. In case of maintenance the system provides a manual bypass line, which also can be monitored by the flowmeter. Herefore, changing a filter cartridge or doing any other service work on the system is quick and easy! As raw and fitting material ASCO uses mainly stainless steel. This makes the system very resistant and extends the products life cycle. easy to install very accurate 4 20 mA output signal robust stainless steel construction no auxiliary equipment like air compressor needed, only power supply is required

• Measurement of DC voltage, DC current, temperature (RTD, TC) and resistance • Programmable remote I/O functionality. Readout of all input variables and internally calculated values via MODBUS. Simultaneously, the outputs and the relay may be controlled via MODBUS. • Free selection as to whether the output variables are dependent on the input variables or whether the outputs are controlled independently of the inputs via MODBUS. • Sensor connection without any external jumpers • 2 inputs (e.g. for sensor redundancy or difference formation) • 2 outputs (U and / or I) • 2 inputs can be linked with each other and allocated to the 2 outputs which enables calculations and sensor monitoring (e.g. prognostic maintenance of sensors) • System capability: Communication via Modbus interface • Freely programmable relay, e.g. for liwith or alarm signalling • AC/DC wide-range power supply unit • Pluggable high-quality screw or spring cage terminal

• Robust transmitter for angular position suitable for field applications • Highest degree of mechanical and electrical safety • Proven capacitive scanning system • No wear, low annual maintenance and mountable anywhere • Vibration and shock-resistant • Measuring range (zero point and end position) and sense of rotation via Modbus/TCP adjusted

Converts the angular position of a shaft into a load independent direct current signal, proportional to the angular shaft position. • Robust transmitter for angular position suitable for field applications • Highest degree of mechanical and electrical safety • Proven capacitive scanning system • No wear, low annual maintenance and mountable anywhere • Vibration and shock-resistant • Measuring range, sense of rotation, zero position and linear/V-characteristic can be adjusted by a switch and two push-buttons • Analog output signal 4…20 mA, 2-wire connection • Zero position and end position are independently adjustable • Capacitive scanning system provides absolute position immediately after activation • Suitable for ocean-going vessels acc.
