Installation and Maintenance Instructions for

28HPX High Purity Gauge

TROUBLES

The pointer does not move.

The pointer does not indicate

pressure.

The pointer does not read zero

when the pressure gauge is

removed from the piping.

The pointer indicates overpressure

reading.

CHECKPOINTS

1. Check if the pressure had been

applied to the pressure gauge.

1. Check whether the fluid and

ambient temperature are within

the operating temperature

range of the pressure gauge.

2. Check whether excessive

vibration exists.

3. Check whether excessive

pressure fluctuations exist.

1. Check whether excessive

pressure had been applied.

2. Check whether excessive

vibration or fluctuating pressure

had been applied.

1. Check whether excessive

pressure had been applied.

2. Check whether the gauge was

exposed to excessive vibration

or if it was dropped/impacted.

POSSIBLE CAUSES

1. The pressure is zeroed.

1. The operating temperature

range has been exceeded.

2. Movement wears due to

vibration.

3. Movement wears due to

pressure fluctuations.

1. The diaphragm has been

deformed due to excessive

pressure.

2. Movement wears due to

vibration or fluctuating

pressure.

1. Deformed sensing element due

to excessive pressure.

2. Pointer shift or material

deformation due to excessive

pressure or impact.

COUNTERMEASURES

1. Apply pressure.

1. Re-install pressure gauge in a

different position.

2. Re-install pressure gauge in a

different position.

3. Reduce pressure fluctuations.

1. Use a higher pressure range.

2. Re-install pressure gauge in a

different position.

1. Use a higher pressure range.

2. Be careful not to drop/impact

gauge.
