Characteristics
- Type
- 12MT 100EK; 12MT 160EK; 22MT 100EK; 22MT 160EK
- Nominal size (ND)
- 100, 160 mm
- Accuracy class
- With sliding contacts – 1.6 (1) With magnetic snap-action contacts – 2.5 (1.6)
- Measuring ranges
- -1…0 to 0…600 bar
- Connection
- Radial (R) Axial (AE)
- Application
- For switching electrical circuits at preset limit values of the measured pressure or vacuum. Suitability for the measured fluid is determined by the pressure gauge on which the electric contact device is installed.
Technical specifications
| Technical specifications | 12 MTEK | |
|---|---|---|
| Nominal size in mm – ND | 100 | 160 |
| Permissible temperatures | Ambient: Tmin -20°C; Tmax +60°C Fluid: Tmax +100°C | |
| Number of contacts | 1, 2 or others | |
| Contact types | Sliding contacts – S Magnetic snap-action contacts – M | |
| Connection schemes | Any combination of normally open (NO) and normally closed (NC) contacts with the pointer at “0”. Contact numbering increases in the direction of pointer deflection from “0”. | |
| Important | For frequent switching, operation with a control relay is recommended. Liquid filling extends the life of the mechanical assembly but increases deposits on the contact pins. An impulse-controlled MSR multifunction relay is recommended: power up to 1840 VA, voltage up to 250 V and current up to 8 A. | |
