AT THE HEART OF M4 PRODUCTS - MEMOSENS

Memosens* is a digital connection and communication protocol for analytical sensing technology. When using Memosens, a quality signal is assured through the use of a hermetically sealed, galvanically isolated, inductive connection. Calibration and sensor condition are continuously monitored and stored in the sensor head.

Benefits:

Galvanically isolated
Inductive electrical connection assures disturbance-free data transfer
Calibration data stored in the sensor head
Digital communication eliminates external interference and assures that calibration data is assigned to the correct sensor
Predictive maintenance
The sensor continuously monitors:
- Wear
- Glass impedance
- Zero point
- Slope
- Response time
- Calibration intervals
Submersible due to hermetically sealed sensor head
Memosens is an open-architecture digital protocol that is supported by several manufacturers as their standard

M4 Knick Sensogate Retractable Holders

The SensoGate® has a manual rotary drive, which enables the fitting to be operated up to a counter pressure of 145 psi (10 bar) – and this in less than two rotations. Regardless of how unfavorable the angle or the operating height at which the fitting is installed. Little rotary force is required and is easily applied manually. This is not possible with the sliding motion of conventional retractable fittings.

Benefits:

Compact, buildup resistant design
Low maintenance
Simple replacement of seals due to divided calibration/cleaning chamber
Increased service life and reduced seal wear
Low cost, simple installation, operation, and maintenance
SensoLock for high operational safety
Integrated limit switches
Fast and easy replacement of calibration chamber and insertion tube
All maintenance can be performed on site
Cyclone cleaning effect
Standard sensor length (225 mm) even for large immersion depths
Multiple process connections available
Flange version with scraping ring
Modular design allows specific replacement of the process-wetted materials: PEEK, PVDF, PP, 316 SS, Hastelloy
Plastic versions with high pressure and temperature resistance due to carbon fiber reinforced plastics
Special version for sensors with pressurized liquid electrolyte
