Beschreibung

The P640 series are designed to measure differential pressure from 25 kPa to 2.0 MPa at static pressure 10 MPa and have electrical contact. A set of two stainless steel bellows mounted on a force balance allows direct reading of the actual differential pressure.

Nominal diameter	150 mm
Accuracy	±1.0 % of full scale ±1.5 % of full scale
Scale range (MPa, kPa, bar, mbar)	0 ~ 25 kPa to 0 ~ 0.25 MPa (P641 model) 0 ~ 0.4 MPa to 0 ~ 2.0 MPa (P642 model)
Static pressure	Max. 10 MPa
Working temperature	Ambient : -20 ~ 65 °C Fluid : Max. 100 °C
Degree of protection	EN60529/IEC529/IP55
Temperature effect	Accuracy at temperature above and below the reference temperature (20 ℃) will be effected by approximately ±0.5 % per 10 ℃ of full scale
Pressure connection	Stainless steel (316L SS), Monel and Hastelloy-C
Element	Bellows Stainless steel (316L SS), Monel and Hastelloy-C
Case and cover	ALDC12.1, Black painted Screwed type
Window	Safety glass
Dial	White aluminium with black graduations
Filling liquid for differential cell	Silicone oil
Pointer	Black painted aluminium alloy (Zero adjustable)
Contact	Contact rating : AC 250 V 3 A / 125 V 5 A DC 250 V 0.2 A / 125 V 0.4 A / 30 V 4 A Dielectric strength : AC 500 V / MIN Type : Micro contact, One and two SPDT
Conduit connection	¾" PF(F)
Process connection	¼" NPT(F) ½" NPT(F) at 3-way and 5-way manifold valve
Standard accessories	Mounting bracket for 2" pipe mounting with silver gray finished steel
Option	■ Remote seal - Not available with less than 40 kPa of differential pressure range ■ Mounting bracket with 316SS for 2" pipe ■ 3-way manifold valve (316SS, Monel) ■ 5-way manifold valve (316SS, Monel)
