WIKA A-10 Pressure Transmitter
Overview
WIKA A-10 is a compact pressure transmitter engineered for general industrial and OEM applications, offering excellent measurement quality at an extremely competitive price. Precision engineered with an all-stainless steel welded measuring cell, the WIKA A-10 pressure transmitter provides reliable resistance to vibration, shock, wide temperature variations, and RFI, making it a proven choice for machine building, shipbuilding, measurement and control technology, and hydraulic and pneumatic systems worldwide.
As the official authorized partner and exclusive regional representative for WIKA, Seven Star LLC proudly supplies the WIKA A-10 pressure transmitter to industrial, OEM, and process customers across Oman and the wider GCC. Every unit shipped through Seven Star LLC is genuine WIKA product with full manufacturer warranty and access to local technical support – ensuring facility engineers and procurement teams in Muscat, Sohar, and Salalah receive an authentic, factory-certified WIKA A-10 backed by regional service.
Working Principle
The WIKA A-10 measures pressure using a piezoresistive sensor built with thin-film sensor technology, mounted within an all-stainless steel welded measuring cell. As process pressure is applied to the sensing element, the resulting mechanical strain changes the electrical resistance of the piezoresistive elements in a Wheatstone bridge configuration; this change is measured and conditioned by onboard electronics to produce a linear, calibrated output signal proportional to pressure. Because the measuring cell is fully welded, the WIKA A-10 eliminates the soft sealing materials found in many competing designs, which can deteriorate and cause drift or leakage over the life of the instrument.
This all-welded construction gives the WIKA A-10 its defining reliability advantage: with no elastomeric seals in the pressure path, the transmitter maintains long-term measurement stability even under repeated pressure cycling, shock, and vibration. Users can select between two non-linearity classes, 0.5% or an improved 0.25% BFSL, to match the accuracy requirements of the application, and every transmitter ships with a free test certificate documenting the measuring points recorded during manufacture.
Engineering Design of the WIKA A-10
The WIKA A-10 covers an exceptionally wide range of measuring spans, from 0 to 0.05 bar up to 0 to 1,000 bar (0 to 1 psi up to 0 to 15,000 psi), with a 316L stainless steel pressure connection for the wetted parts. Standard process connections include G ¼ A per DIN EN ISO 1179-2, ¼ NPT, ½ NPT, SAE #4, and other configurations available on short lead time, while electrical connections span angular connector forms A and C, circular M12x1 connector, and a 2 m (6 ft) cable outlet, among other options.
Signal output options include the industry-standard 4 to 20 mA two-wire loop, along with DC 0 to 10 V and DC 0 to 5 V ratiometric outputs for direct compatibility with a wide range of PLC and control system input cards. Power supply requirements are 8 to 30 VDC for current output (14 to 30 VDC for voltage output models), and the transmitter is rated for operating temperatures from 0°C to +80°C (32°F to +176°F). Overvoltage protection to 32 VDC (36 VDC on 4-20 mA models) and short-circuit protection add further robustness for industrial wiring environments, and international cULus and EAC certification supports worldwide deployment.
