Superior Pressure Transmitter S20 WIKA

Superior pressure transmitter model S20 WIKA

A pressure sensor (pressure transmitter) converts the physical quantity ‘pressure’ into an industry-standard signal. WIKA portfolio covers a wide spectrum of pressure sensors: for refrigeration and air-conditioning applications, the food industry, mobile working machines, medical gases, and the semiconductor industry. WIKA pressure sensors offer accuracies starting from 0.05 %, measuring ranges from 20inWc … 200,000 psi, digital interfaces such as CANopen and IO-Link, multiple international approvals, hazardous areas.

Superior Pressure Transmitter S20 WIKA

The model S-20 pressure transmitter for general industrial applications is the ideal solution for customers with demanding measuring requirements.

It features a very good accuracy, a robust design and an exceptional number of variants, meaning it can be suited to the widest range of applications. Versatile The model S-20 offers continuous measuring ranges between 0 … 10 to 0 … 20,000 psi (0 … 0.4 and 0 … 1,600 bar) in all the major units.

These measuring ranges can be combined in almost any way with all the standard industry output signals, the most common international process connections and a wide number of electrical connections. Furthermore, it offers numerous options, such as different accuracy classes, extended temperature ranges and customer-specific pin assignments. High quality The robust design turns the model S-20 into a very high-quality product, which even the most adverse environmental conditions cannot affect. Whether with the lowest temperatures when used outdoors, with extreme shock and vibration in machine building or with aggressive media in the chemical industry, this transmitter can meet all requirements. Availability All variants described in this data sheet are available on very short lead times. For particularly urgent demands, there is a sizeable stock available.

Output signal

Current (2-wire)

• 4 … 20 mA

Voltage (3-wire)

• DC 0 … 10 V
• DC 0 … 5 V
• DC 1 … 5 V
• DC 0.5 … 4.5 V
• DC 1 … 6 V

Ratiometric (3-wire)

• DC 0.5 … 4.5 V

Power supply

• Maximum power supply for cULus approval: DC 35 V (DC 32 V with heavy-duty connector)

Overpressure limit

• The overpressure limit is based on the sensor element used. Depending on the selected process connection and sealing, restrictions in overpressure safety can result. A higher overpressure limit will result in a higher temperature error
