OneFunction Introduction:
The EPC1000 series electrical converter can convert different input current signals into corresponding output pneumatic signals. There is a pneumatic power amplifier inside the converter, which can obtain pneumatic signals with high output power to various pneumatic actuators (large-diameter regulating valves) to improve the action speed of the actuators, in addition to serving as a conversion unit between electric instruments and pneumatic regulating valves. It can also be used in conjunction with pneumatic valve positioners to achieve the function of electrical valve positioners. This product has the advantages of small size, clever structure, high precision, good stability, and easy installation.
IITechnical parameters:
1. Gas source pressure range: minimum value: 20kPa higher than the upper limit of output pressure; Maximum value: 700kPa. 2. The influence value of gas source pressure on output: ≤ ± 0.5% of span 10kPa (in the medium range). 3. Linearity: ≤ ± 1% of span. 4. Repeatability: ≤ ± 0.5% of span. 5. Return difference: ≤ ± 1.0% of span. 6. The minimum air circulation capacity is 7.6m3/h (standard state) at a medium range of 175kPa air source pressure and 20m3/h (standard state) at a 700kPa air source pressure. 7. Environmental conditions: Temperature: -30 ℃ to+60 ℃; Humidity:<85%. 8. Maximum static air consumption: 0.3m3/h (standard state) for medium range use. 9. Connection size: Gas path connection port: Gas source card sleeve type gas tube head (φ 6 copper tube); Output signal: sleeve type tracheal joint (with a diameter of 6 copper tube); There are two types of output pneumatic pressure gauges: 0-160kPa and 0-250kPa, or they can be selected according to the output pressure; Electrical interface: G1/2 ". 10. Dimensions: Ordinary and intrinsic safety types: 87mm × 160mm × 107mm; Explosion proof type: 97mm × 186mm × 202mm 11. Weight: 0.9kg for regular and intrinsic safety types, 2.35kg for explosion-proof types.
IIIProduct features:
1. This converter is a direct acting (no feedback) instrument that can obtain high-power pneumatic output signals. 2. Beautiful appearance, clever structure, small size, and light weight. 3. High sensitivity, good stability, and moderate accuracy (especially suitable for output circuits). 4. The mode of action can be directly changed on site. 5. Externally equipped with span and zero adjustment devices, easy to calibrate and maintain. 6. The internal circuit of the converter is equipped with a thermistor, which can automatically perform temperature compensation. 7. Wide gas supply range, suitable for various occasions. 8. This converter can be directly used for different input electrical signals, such as 4-20mADC or 0-10mADC. Its output pressure can also be divided into ranges such as 20-60kPa or 60-100kPa. To achieve the above objectives, simply adjust the "zero position" and "span" adjustment devices. 9. Low gas consumption. 10. Can be installed at any angle (note: the working installation angle position should match the calibration angle position). 11. Explosion proof performance: intrinsic safety explosion-proof grade ia Ⅱ CT5 explosion-proof grade d Ⅱ BT6.
7The components are formed by precision die-casting, with exquisite manufacturing processes for both exterior and internal structure, and a compact overall structure.
8Adopting stainless steel fasteners and advanced spray coating technology, it has good anti-corrosion performance.
