The EPC pressure switches are available as standard and to DESINA conformity.They are equipped with a 4-digit, 7-segment display, its 7 mm high red numbers can be read easily in all conditions. The device can be rotated by 280°, is made of cinc die casting with polyester cover foil and powder-coated with crimson color (RAL 3004).

• Measuring instrument with digital pressure display
• One/two threshold switches, separately programmable(exceedance / undercut of a pre-defi ned pressure)
• Analog output (presentation of the pressure profi le)
