Select a flameproof pressure transmitter with Ex d type certification,
and a 4-20mA output signal for installations,
which require the use of devices & enclosures,
which are designed to contain internal explosions,
to prevent ignition of explosive atmospheres surrounding the equipment,
in designated flameproof zones.
Features of SIEP489 Explosion-proof pressure transmitter
- FM approved as “explosion-proof” for class I, div. 1 hazardous areas
- Available with ATEX approval “flameproof enclosure” for II 2 G Ex d II C
- Current or voltage output

The Series SIEP489 Smart Pressure Transmitters have been designed,
for the high demands of industrial oil and gas applications.
The Series SIEP489 is capable of being configured with the zero and span buttons,
a field calibrator is not required for configuration.
The transmitter software compensates for thermal effects,
The Series 3200G is FM approved for use in hazardous (Classified) locations.
The 40:1 rangeability allows the smart transmitter,
to be configured to fit any application.
These pressure transmitters can be delivered with analog signals including 4 … 20 mA or a low-power version with 1 … 5 VDC.
They feature exceptionally high resistance to vibration,
pressure spikes and moisture ingress.
these pressure transmitters fulfil IP 67 (NEMA 4x) ingress protection.
On each individual instrument,
comprehensive quality control and calibration are performed,
so that an accuracy of ≤ 0.25 % BFSL can be ensured.
Temperature compensation guarantees accuracy and long-term stability, even with strong fluctuations in the ambient temperature.
The models SIEP489 are suitable for sour gas applications,
and feature particularly high resistance,
against sulfide stress cracking when in contact with sulfurous gases.
The pressure transmitters are approved as “explosion-proof” for class I, II, III, Div. 1 hazardous area to FM and CSA,
as well as “flameproof” for II 2 G Ex d II C to ATEX.

What is specified by the temperature coefficient and how is it important to my readings?
As the ambient temperature changes, the output current will drift slightly.
The temperature coefficient specifies the amount of drift per °F/°C.
Since the temperature affects the transmitter output,
the temperature coefficient is important to accuracy of your reading.
Know More About Explosion-proof pressure transmitter
Explosion-proof pressure transmitters are available in a wide range of specifications,
easy to install and use, safe and explosion-proof.
They can be widely used in petrochemical, electric power, metallurgy, pharmaceutical, food processing, and other industries.
Products comply with the “IEC” standard, and explosion-proof pressure transmitters are internationally renowned.
The company’s high-precision, high-stability pressure sensor components,
through high-reliability amplifier circuit and precise temperature compensation,
convert the absolute or gauge pressure of the measured medium into 4~20mA, 0~5VDC, 0~10VDC, and 1~5VDC.
Such as standard electrical signals.
High-quality sensors hermetically sealed soldering technology,
and a complete assembly process ensures excellent quality and performance.
The product is available in a variety of interface styles,
and a variety of lead styles to best meet customer needs,
and is suitable for use with a variety of measurement and control equipment.
Explosion-proof pressure transmitter working principle
The explosion-proof pressure transmitter consists of an integrated intelligent sensor and peripheral circuits.
The sensor part is composed of a pressure sensor,
a signal modulation circuit, a dedicated digital processing chip,
a temperature sensor and data memory,
and the peripheral electronic circuit part is composed of an LCD display,
function keys and an EMC circuit.
The pressure signal is converted into an electrical signal by the pressure sensor,
and the electrical signal is modulated,
and sent to a dedicated digital processing chip for data processing,
and then converted into a 4~20 mA output signal corresponding to the pressure signal,
and the HART digital signal is superimposed on the current signal for communication.
