Introduction

SPT28 series of digital pressure gauge for the whole electronic structure, battery-powered, on-site installation is simple. It uses high precision piezoresistive pressure sensor, low temperature drift amplifier amplification processing, and high-precision A / D converter. After signal is converted into digital signal, The LCD display shows the actual pressure value.

The intelligent digital pressure gauge is very flexible, easy to operate, battery supply, safe and reliable. Widely used in hydropower, water, petroleum, chemical, mechanical, hydraulic and other industries which need pressure local display .

Specifications

Outline Construction

Installation

The SPT28 can be mounted directly on the hydraulic line via a pressure fitting (M20 * 1.5) (other sizes available on order). In critical applications such as severe vibrations or shocks, pressure fittings can be mechanically decoupled via miniature hoses.

NOTE: Vertical installation must be carried out when the range is less than 100 kPa.

Operating Instructions:

1. Measurement status:

• On, off: short press "ON / OFF" button

• unit switch: long press "ON / OFF"

• Peak Clear: Short press "ZERO" key

• Clear display: press "ZERO" key(Note: This function is only used under no pressure)

2. Setting Status:

• "ZERO" key: short press to modify the current flashing digit value or down menu, long press to move the flashing digit position

• "ON / OFF" key: Short press to change the current parameter value (the highest digit blinks) or confirm the current modification parameter value (the value stops blinking)

3. Parameter setting:

• "Locd": password input menu, enter the password "1000"

• "offt": automatic shutdown time menu, set the range of "00 ~ 15" minutes, "00" for continuous work

• "bclt": backlight open time menu, setting range "00 ~ 15" minutes, "00" to turn off the backlight

• "End-": exit the menu, set the value "0 ~ 1" "0" to exit without saving the setting parameters, "1" to exit the setting parameters

4. Setting method:

1. Press "ZERO" and "ON / OFF" at the same time, and when "LOCK" is displayed on the secondary screen, input "1000" and press "ON / OFF" to confirm, enter parameter setting status

2. Short press "ZERO" to select the menu to be modified

3. Press the "ON / OFF" key briefly to allow modification of the parameters

4. Short press the "ON / OFF" button to confirm the change

5. Short press "ZERO" to select "End-" menu
