KPS210 Hammer Union Pressure Sensors
1.Introduction
KPS210 strain gauge high pressure transmitter is a new product that integrates foreign advanced technology and domestic sensor manufacturing technology. It is another crystallization of our company's introduction and digestion of foreign product technology. The sensor adopts imported, high-precision, large resistance strain gauge and domestic unique diaphragm technology. Its measurement range can reach 160Mpa, and it has the characteristics of high response, high precision, strong structure, corrosion resistance, vibration resistance, high performance and high cost performance.
The product is widely used in drilling equipment in the oil industry, especially for high-pressure measurement of imported fracturing vehicles and cementing vehicles. It is the preferred transmitter to replace imported products.
This explosion-proof type meets the requirements of GB3836.1-2010 and GB3836.4-2010 standards, and has obtained the explosion-proof certificate. The explosion-proof mark is Ex ib IIB T6 Gb.
The explosion-proof product is suitable for occasions where explosive gases may appear. The corresponding explosion-proof areas are Zone 1 and Zone 2, and its typical representative gas is propane.

4. Transport, packaging and storage
4.1 Transport
Check whether the instrument has been damaged during transport. If there is obvious damage, please contact us.
4.2 Packaging and storage
Do not remove the packaging before installation.
4.3 Permissible conditions for storage:
Storage temperature: -40~+70 °C
Storage humidity: 45%~75% relative humidity (no condensation)
5. Installation
The pressure sensitive element used in this product transmits pressure through the pressure-sensitive diaphragm. Any touch will cause damage to the transmitter.
▶ Do not touch the inside of the pressure interface in any way.
5.1 Installation preparation
Check that the appearance of the transmitter is good;
The sealing surface of the pressure interface of the transmitter is clean and undamaged;
Consider the applicability of the measured medium;
The ambient temperature and medium temperature must be within the product technical specifications;
There is enough space for safe electrical installation.
5.2 Transmitter installation and sealing method: Union 2”#1502
5.3 Transmitter electrical system
The product matching plug-in is a waterproof plug-in. To ensure the product protection level, be sure to lock the connector during electrical connection.
Power supply: See the product label for details (the power supply must meet the requirements of relevant standards, and the power supply system should be reliable.) The intrinsically safe explosion-proof transmitter is powered by a safety barrier.
Electrical connection requirements: Select a cable with a diameter that matches the plug cable gland, and the cable gland and plug must be intact.
Electrical connection requirements: See the product label for wiring definition
Product pin definition:
A (red): power supply V﹢
B (black): signal output OUT (two-wire system)
C: empty
D: empty
E (yellow): reset + (calibration)
F (white): reset - (calibration)
5.4 Intrinsic safety transmitter for explosive gas environment use precautions
When intrinsically safe explosion-proof transmitters are used in explosive gas environments for electrical connection, they should be combined with safety barriers to form an intrinsically safe explosion-proof system. The safety barrier and power supply are placed in a safe area, and the intrinsically safe transmitter is placed in a dangerous area. Pay attention to safe grounding.
5.5 Intrinsic safety transmitter for explosive gas environment use precautions
When intrinsically safe explosion-proof transmitters are used in explosive gas environments for electrical connection, they should be combined with safety barriers to form an intrinsically safe explosion-proof system. The safety barriers and power supplies should be placed in the safe area, and the intrinsically safe transmitters should be placed in the dangerous area. Pay attention to safe grounding.
The two-wire 4~20mADC output intrinsically safe system is shown as follows:
The maximum allowable distributed capacitance Cc=Co-Ci, the maximum allowable distributed inductance Lc=Lo-Li of the system connection cable between the transmitter and the safety barrier.
The maximum allowable distributed capacitance Cc=Co-Ci,
The maximum allowable distributed inductance Lc=Lo-Li.
